iBrid Multi-Gas Sensor Warnings and Cautionary Statements

Revision 1.0 (p/n: 17136193) INDUSTRIAL SCIENTIFIC v

WARNINGS AND CAUTIONARY STATEMENTS IMPORTANT: Failure to perform certain procedures or note certain conditions may impair the performance of this product. For maximum safety and optimal performance, please read and follow the procedures and conditions listed below.

IMPORTANT: Read and understand this manual before operating.

Oxygen deficient atmospheres may cause combustible gas readings to be lower than actual concentrations.

Oxygen enriched atmospheres may cause combustible gas readings to be higher than actual concentrations.

Verify the calibration of the combustible gas sensor after any incident where the combustible gas content has caused the instrument to display an over-range condition.

Silicone compound vapors or other known contaminants may affect the combustible gas sensor and cause readings of combustible gas to be lower than actual gas concentrations. If the instrument has been used in an area where silicone vapors were present, always calibrate the instrument before next use to ensure accurate measurements.

Sensor openings and water barriers must be kept clean. Obstruction of the sensor openings and/or contamination of the water barriers may cause readings to be lower than actual gas concentrations.

Sudden changes in atmospheric pressure may cause temporary fluctuations in the oxygen reading.

Charge battery, service unit, and use its communication port only in non-hazardous locations. Not for use in oxygen-enriched atmospheres.

WARNING: Substitution of components may impair intrinsic safety and may cause an unsafe condition. AVERTISSEMENT: La substitution de composants peut compomettre la securite intinseque.

CAUTION: For safety reasons, this equipment must be operated and serviced by qualified personnel only. Read and understand the instruction manual completely before operating or servicing. ATTENTION: Pour des raisons de sécurité, cet équipment doit étre utilesé entretenu et réparé uniquement par un personnel qualifié. Étudier le manuel d'instructions en entier avant d'utiliser, d'entretenir ou de réparer l'équipement.

CAUTION: High off-scale readings may indicate explosive concentration. ATTENTION: Des lectrures supérieures a l'échelle peuvent indiquer des concetratoins explosives.

CAUTION: Any rapid up-scale reading followed by a declining or erratic reading may indicate a gas concentration beyond the upper scale limit which may be hazardous.

1.2. Hardware Components Hardware components of the iBrid multi-gas instrument include the following:

• Chassis • LCD • Five-way navigation button • Sensors • Audio indicator • Vibrating alarm • Visual alarm • IR communications port • Clips/connectors • Charger.

These components are shown in Figure 1-1 and are explained in the sections that follow.

Introduction iBrid Multi-Gas Sensor

1-2 INDUSTRIAL SCIENTIFIC Revision 1.0 (p/n: 17136193)

1.2.1. Chassis The iBrid multi-gas instrument has a rugged chassis that is temperature hardened to withstand operating environments from -20° C to +55° C (-4° F to +131° F). It has optional clips and a wrist strap, plus molded sides making it easy to grip.

1.2.2. LCD The display is a graphical, color LCD with a software-controlled backlight. The backlight is enabled for 5 seconds each time a button is pressed. Any additional button press during the 5 seconds resets the timer for an additional 5 seconds. The screen uses a 65K color palette (including a gray scale) for displaying information.

1.2.3. Five-Way Navigation Button A single five-way navigation button provides easy positioning and item selection from the LCD. The navigation button allows the user to do the following:

• move the cursor to the left, right, up, and down • change the current “focus” (that is, which item on the LCD is currently highlighted) • select a menu item or focus item (using the “enter” button in the center).

Most of the menu navigation is controlled by a simple, single button push, though some operating modes are only accessible by holding the buttons for an extended period of time, or by pressing the buttons twice.

Down

Left Right

Enter

Figure 1-2. Five-Way Navigation Button

NOTE: The backlight of the LCD is enabled for 5 seconds each time a button is pressed. Any additional button press during the 5 seconds reset the timer for an additional 5 seconds.

1.2.4. Sensors The iBrid multi-gas sensor may contain up to six internal sensors, depending on how it is configured. The sensors are located in the top portion of the instrument chassis. Sensor openings in the chassis permit the sensors to monitor ambient gases. A gas-permeable filter covers the sensor openings to limit the amount of dust and contaminants that might enter the internal sensor chamber and affect sensor readings. An enlarged view of the sensor openings is shown below.



NOTE: Though there appears to be only five sensor locations based on the sensor opening (as illustrated above), one of the positions may contain a dual sensor, providing a maximum of six sensors. The specific location of actual sensors is discussed later in this manual.

Figure 1-3. Sensor Openings (Enlarged to Show Detail)

The actual sensors used in the iBrid instrument are temperature-compensated using an on-board temperature sensor. This enables the instrument to provide accurate readings across the full temperature range of the instrument.

1.2.5. Audio Indicator The software of the instrument controls both the tone of the “beep” and the delay between the beeps of the audio indicator, which is used for alarming. There are two levels of audio gas alarms:

• low-level (or level-1) alarm • high-level (level-2) alarm.

The level-1 alarm utilizes a lower frequency beep with a longer delay, while the level-2 alarm utilizes a higher frequency tone with a shorter delay between the beeps. For all sensors but oxygen, if the gas reading is above the high alarm level, the instrument sustains the high alarm until the gas reading is below the high alarm level, then the instrument switches to the low alarm until the gas reading is below the low alarm level. For the oxygen sensor, a high alarm only is indicated for both oxygen enrichment and depletion.

Other uses of the audio alarm include STEL and TWA alarms, as well as calibration and zero failures.

NOTE: A simple “beep” is also utilized for conditions that warrant a warning, but not an alarm. The audio indicator is also used as a confidence indicator. This indicator, when enabled by the user, beeps once every 30 seconds.



1.2.6. Vibrating Alarm The instrument has an optional vibrating alarm that is used for limit alarms and as a confidence indicator. When enabled by the user, this alarm vibrates for 1-2 seconds approximately every 30-60 seconds.

1.2.7. Visual Alarm The instrument has alarm LEDs located beneath the opaque sensor array at the top of the unit. During an alarm, the LEDs are activated and illuminate the upper portion of the iBrid. For level-1 alarms, the LEDs are pulsed on and off with a longer delay between pulses. For the level-2 alarms, the LEDs are pulsed on and off with a shorter delay. The LCD backlight flashes as part of all alarm sequences, except for the battery low condition.

The visual alarm is also used as the confidence indicator which, when enabled, blinks the LEDs once every 30 seconds.

1.2.8. I/R Communications Port An optical media interface is located on the bottom on the iBrid instrument and is used for infrared (I/R) data transmissions. This interface adheres to the IrDA physical layer specification and supports speeds greater than 115200 bytes/second (known as the Fast Infrared transmit mode or FIR).

1.2.9. Clips/Connectors A clip located on the back of the iBrid may be used to secure the unit (to a jacket or suspenders, for example) for hands-free gas monitoring. In addition to the non-slip rubber overmold and ergonomic design, a wrist strap is also provided to protect against drops during user operation.

1.2.10. Chargers Three different chargers are available for use with the iBrid multi-gas sensor:

• Charger • Datalink • Charger/Datalink Combination.

The charger is used to charge the internal batteries of the iBrid device. A combination transformer and power cord is supplied with the charger. The Datalink charger is used to download data for data logging from the iBrid unit directly to a host computer. The combination charger offers both capabilities. The three chargers look very similar and are shown below.

Figure 1-4. The Charger, DataLink, and Combination iBrid Charging Cradles



1.3. Features Overview Some of the key features of the iBrid multi-gas instrument include the following:

• User interface • Security function • Alarm events • Error events • Data logging • Multiple language support • Communications interface • Memory.

These features are explained sections that follow and throughout this manual.

1.3.1. User Interface Features In general, a user interface is the place where a human user can interact with a machine. This place usually contains physical components that facilitate the transfer of information in either one direction or both directions. In the case of the iBrid multi-gas instrument, the user interface contains the following components:

• LCD • Navigation Button • Audio Indicator • Vibrating Alarm • Visual Alarm.

The LCD of the iBrid instrument is menu driven and similar to that of cell phones and PDAs. It consists of two different main menus:

• Normal Operation Menu (white background on LCD) • Configuration Menu (yellow background on LCD).

The background color of the LCD can be used to identify the current menu. The Normal Operation Menu has a white background. The Configuration Menu has a yellow background. See the example below.

Figure 1-5. Normal Operation Menu (White) vs. Configuration Menu (Yellow)

During Normal Operation Mode, the menu bar is hidden, but can be displayed by pressing the center [ENTER] navigation button. The menu bar has a five-second time out. If no button is pressed within five seconds of the menu being activated, it is deactivated.



1.3.2. Security Feature Access to the Configuration Menu is protected using a security password. This password must be entered in order to access and change the parameters within the Configuration Menu.

NOTE: The instrument is shipped with no password. To take advantage of this security feature, the user must create a password. This is discussed later in this manual.

Figure 1-6. Password Screen for Accessing the Configuration Menu

1.3.3. Alarm Events Fifteen alarm events for the instrument are recorded into non-volatile memory and are time stamped. After fifteen events are saved, the earliest one is over-written with the latest to provide continuous loop logging. An event is recorded any time that the instrument goes into alarm. The information stored for each event includes:

• instrument serial number • sensor type • sensor serial number • gas type • peak exposure level • alarm duration in minutes and seconds • date and time that alarm occurred.

NOTE: These alarm events can be downloaded from the instrument.

1.3.4. Error Events Fifteen error events for the instrument are recorded into non-volatile memory and are time stamped. After 15 events are saved, the earliest one is over-written with the latest providing continuous loop logging. An error event is recorded any time that a fault occurs within the instrument, and includes pump faults and fault events during the self-test.

The information stored for each event includes:

• instrument serial number • fault that occurred • fault error code • date and time stamp.



1.3.5. Datalog Data logging is a feature that allows a variety of system parameters to be recorded at regular intervals (and saved internally) for retrieval (and viewing) at a later date. The datalog feature of the iBrid instrument saves the following information:

• Gas Type • Battery Level • Gas Reading • User ID • Time of Day • Site ID • Date • STEL • Temperature • TWA • Alarm Conditions Flagged • Snapshot Enabled/Disabled.

NOTE: As a reference, data saved for one year can be downloaded within 15 minutes.

NOTE: Data is saved in case of power loss.

1.3.6. Memory Three key types of information storage areas are included in the iBrid multi-gas instrument:

• Data Flash Memory • SDIO • Sensor/DAS EEPROM.

The iBrid instrument has 4 MB of on-board data flash memory. This amount of memory is cable of storing (at a minimum) the following, simultaneously:

• 3 months of data collected at 1 minute intervals for 5 sensors (6 gases) • 60 alarm events per day over a 1 year period • Instrument configuration parameters (i.e., serial number, date of manufacture, etc.) • Dynamic response factors for the PID sensor • Correlation factors for the LEL sensor • Event log (15 entries per instrument).

The SDIO flash card is able to store (if necessary):

• Documentation (i.e., text files of user guides, NIOSH information, manuals, training, etc. The maximum file size is 4 KB.)

• Company-specific bitmap and/or background watermark read from card • Code for firmware updates.

The instrument has an SDIO card for storing information. The SDIO card uses a FAT (File Allocation Table) system as a memory manager and the iBrid software communicates with the card to store and retrieve the information as needed. The sensor-specific information is stored on the sensor’s DAS EEPROM.



1.3.7. Communications Interface The iBrid instrument utilizes optical media interfaces for infrared data transmission (IrDA) at a speed of 115200 bytes/second.

1.3.8. Multiple Language Support All user interfaces of the iBrid instrument are available in the following languages:

• English • Bahasa • French • Italian • Spanish • Portuguese • German • Dutch.

All of these topics are included in this chapter to provide a general flow of the startup process. Specific operational details are provided later in this manual.

3.2. Unpacking the Instrument When you receive your iBrid, save all shipping and packing material in case the product ever needs to be returned to Industrial Scientific. Before operating the instrument, be sure to do the following:

• Check for obvious shipping damage • Verify your order for completeness.

If you notice any shipping damage or if your order is incomplete, please contact Industrial Scientific.

3.3. Prerequisites Prior to starting up the iBrid instrument, the user should be familiar with a few basic concepts and prerequisites. These include:

• Charging the battery • Menu operation basics.

Experienced users, or those who are familiar with other Industrial Scientific instruments may choose to skip the Operational Basics section.

3.3.1. Charging the Battery The iBrid multi-gas instrument is powered using an internal rechargeable battery. This battery is charged before it leaves the factory, but should be fully recharged prior to use. To charge the battery, follow the steps listed below:

Normal Operation Mode iBrid Multi-Gas Sensor


1. Insert the power cord of the charger into an appropriate wall outlet.

2. Place the instrument in an appropriate charging cradle (Charger or Charger/DataLink) shown below.

3. Note that the LCD on the iBrid should show that the iBrid is charging.

4. Wait approximately eight (8) hours for the iBrid to be fully charged (at 20-25 °C). The MX6 iBrid screen will show “Charge Complete.”

Figure 3-1. The iBrid Charging Cradles (Charger and Combination Charger/DataLink)

If the instrument is placed in a Datalink or DS2, the display shows that the battery is charging. If the Datalink or DS2 is communicating to the instrument, the blue icon in the lower left corner will be displayed.

If the instrument is in the Datalink or DS2 and it is not charging the battery, the display shows the unit connected but the battery not charging. If the Datalink or DS2 is communicating to the instrument, the blue icon in the lower left corner is displayed. The percent bar shows the battery life left in an approximate percentage of total battery life. For 50% or above, the segments is green. If the percentage left is greater than 25% but less than 50%, the segments is yellow in color. If the percentage of battery life left is less than 25%, the segments is red in color.

3.3.2. Menu Operation Basics The actions that are initiated by pressing the five-way navigation button may vary significantly based on (1) the user’s location within the menu structure, and on (2) a particular action item of interest (of many) on one individual screen. Focus refers to a way of identifying that single item (from possibly several items) on the LCD screen.

There are several types of “items” that may be present on any given LCD screen within the menu structure of the iBrid instrument. These items include:

• single function buttons (e.g., OK button) • radio buttons (e.g., select user profile) • check box buttons (e.g., an enable/disable check box) • text box windows (e.g., user-supplied site name) • combo box windows (combinations of these).

Typically, the [LEFT] and [RIGHT] navigation buttons are used to change the current focus and cycle through those items on the screen that allow some form of user intervention. The item that currently has the focus is usually denoted in blue.

Figure 3-3. Sample Displays Showing a Different Focus on Each

The actions of other buttons are typically dependent on the type of item that has focus. For example, when a checkbox control has focus, the center [ENTER] navigation button toggles the check on and off. When a group of radio button controls has focus, the [UP] and [DOWN] navigation buttons are used to switch focus between the controls and the center [ENTER] navigation button is used to complete the selection.

When a text box is displayed, the user changes the value of each character one at a time. Once the focus is on the text box, pressing [ENTER] allows changes to be made to the character values in the text box. The user changes the character value of the field by using the [UP] and [DOWN] navigation buttons. The list of available characters varies by text box. The user advances to the next character using the [RIGHT] navigation button. The user can backspace to the previous character using the [[LEFT] navigation button.

To get the focus on the combo box, the center [ENTER] navigation button must be pressed. If the user presses the [UP] or [DOWN] navigation buttons when the focus is on the combo box, the user can scroll through the list of entries. To select one, the user must press the [ENTER] navigation button once the focus is on the desired entry. Pressing the [RIGHT] or [LEFT] key removes the focus from the combo box.



3.4. Power Up Two key operation basics are powering up the instrument and shutting it down. To power up the iBrid instrument, locate, press and hold the center [ENTER] navigation button for at least 3 seconds.

CHAPTER 4: NORMAL OPERATION MODE

4.1. Overview This chapter outlines how to use the iBrid multi-gas sensor during normal operation. Menus and menu options are explained in detail. These include:

• Normal Reading Screen • View Menu Options • Sensor Menu Options • Datalog Menu Options.

Only menus, menu options, and features that are part of normal operation are included in this chapter. Though configuration menus and options are accessed through normal operation mode menus (specifically, the Configuration option of the View Menu), these options involve more of the programming and setup of the instrument, and therefore are detailed in a separate chapter (Chapter 9: Configuration Menus).

4.2. Normal Readings Screen (NRS) The Normal Readings screen is the default screen displayed while the instrument is in normal operation mode. Each currently installed sensor is displayed. The sensor’s type, unit of measure, and current reading are displayed.

NOTE: Regardless of the physical position in which the sensors are installed, sensors are displayed in the order in which they are calibrated. The instrument determines the calibration sequence that most reduces the risk of cross interference and shall calibrate the sensors in that sequence.

Figure 4-1. Sample Normal Readings Screen Icons indicating current battery status and datalog status (enabled or paused) are displayed in the bottom left corner. The current time is displayed in the bottom right corner.

NOTE: If a PID sensor is installed, the current Response Factor is displayed across the center bottom. If there is no PID sensor is installed, but an LEL sensor is, the current Correlation Factor is displayed across the center bottom. This is user-selectable in the configuration menu

4.2.1. Sensor Layout Based on Installed Sensors Up to six sensors may be installed in the instrument. As a result, the screen layout of sensor information varies based on the number of sensors that are actually installed. Refer to Table 4-2.

Sensor names are displayed as solid black text during normal operation, and blinking black text during alarm conditions. The sensor readings are displayed as solid black numerals during normal operation, and solid red numerals during alarm conditions. Units (e.g., % Vol, ppm, %LEL, etc.) are displayed as black text beneath the sensor readings.

Table 4-1. Screen Display Attributes for Sensor Names and Readings

Display Component Attribute Normal Mode Alarm Mode

Color Black Black Sensor Name

State Solid Solid Color Black Red

Sensor Reading State Solid Solid Color Black Black

Sensor Units State Solid Solid

NOTE: For over range conditions, a blinking “OR” is displayed in color as the sensor reading, rather than the actual sensor value. If the alarm is a STEL or TWA, instead of the sensor reading (value) being shown in red, the word “STEL” or “TWA” is shown in place of the sensor units and the STEL or TWA is shown in red in place of the sensor reading. The STEL and TWA alarms cycle with the gas reading.

NOTE: If there are no sensors installed in the instrument, the No Sensors Installed screen is displayed for 5 seconds, and then the instrument shuts down.

NOTE: Regardless of the physical position in which the sensors are installed, sensors are displayed in the order in which they are calibrated. The instrument determines the calibration sequence that most reduces the risk of cross interference and shall calibrate the sensors in that sequence.



NOTE: Screen illustrations shown in this manual are samples only, and show six-sensor configurations unless noted otherwise.

4.2.2. Sensor Over Range If any sensor during operation detects a value that is outside its operating range, an over range condition occurs and an “OR” is displayed in red and flashes. The instrument alerts the user to the condition audibly and visually. Over range values are those values outside the normal operating ranges of the sensors. These can be found in Table 9-2 in the Specifications chapter.

Figure 4-2. Sample Over Range Display

NOTE: Any over range values in the datalogger, event log, or peaks are clipped at the measurement range of the sensor (e.g., for a CO sensor, the datalogger does not record over 1500 ppm if the instrument goes into over range).

4.2.3. STEL or TWA Alarms If the alarm is a short-term exposure limit (STEL) or time-weighted average (TWA) alarm, instead of the value being shown in red, the word “STEL” or “TWA” are shown on the display to indicate the appropriate alarm.

Figure 4-3. Sample Alarm Display Showing

STEL and TWA Alarms

4.2.4. Pump Fault

If the instrument turns on the Docking Station pump and the pump does not feedback a correct signal, the following screen is displayed on the iBrid’s LCD. The instrument continues to check the pump regularly to see if it can be turned back on.

Figure 4-27. Calibrate Option of The Sensor Menu



Figure 4-28. Calibrate All Sensors Confirmation

Screen

The instrument alarms are deactivated during the calibration to save battery life.

If the [Calibrate] option is selected, the instrument displays the confirmation screen at the right.

If Cancel is selected, the user is returned to the original screen, the screen before the menu bar was enabled.

If the user selects OK, all the installed sensors are zeroed first (following the Zero All steps) and then calibrated. After the zero, the results are shown, for 15 seconds and then the calibration of the first sensor begins.

The screen to alert the user to connect gas to the instrument is then shown.

Figure 4-29. Sample User Alert Screen (Apply Gas) The application of gas will start the calibration. The Skip button will skip the sensor and move to the next sensor. The Abort button will abort the calibration. If a sensor is “skipped,” then the calibration result will be “skipped.”

Once the sensor starts to read gas, the calibration begins. The user has 5 minutes to apply gas before the calibration times out.

If there are six sensors installed in the instrument, the screen on the left is displayed during the calibration. if there is only one sensor installed the screen on the right is displayed.

Figure 4-30. Sample Calibration Status Screens

The progress bar at the bottom of the screen is based on calibrating all the sensors, i.e. when the 100% is reached, all the sensors are calibrated.

A passed sensor is one with a span that is greater than 70% of the cal gas value. These values and the word “Pass” are shown in green on the display. A marginal sensor is one with a span greater than 50% but less than 70% of the cal gas value. These values and the word “Marginal” are shown in yellow on the display. A failing sensor is one with a span less than 50% of the cal gas value. These values and the word “Fail” are shown in red on the display. The instrument stores the calibration result (with date and time stamp) in the DAS memory.

Selecting OK, by pressing [ENTER] when the focus is on the OK button, returns the instrument to the NRS from any of the Calibration Complete screens. If OK is not selected, the instrument returns to the NRS after a 15 second time-out.

All alarms are disabled during calibration of sensors, except for the confidence indicator. The instrument saves the calibration gas concentration, and uses this value to calculate the pass/fail threshold of the span reserve. The instrument saves the minimum and maximum sensitivity values to confirm pass/fail of the calibration. If calibration completes or times out, the instrument remembers the pass/fail results of the calibration. If the calibration is successful, the instrument calculates and stores the new sensitivity and span reserve for use in calculating new gas readings (and for reporting).



4.4.3. Bump Test Under the main menu [Sensor] option, there is a [Bump Test] menu option. If the [Bump Test] option is selected, the instrument displays the following.

Figure 4-32. Bump Test Option of the Sensor

Menu

Figure 4-33. Bump Test Confirmation

Screen

If Cancel is selected, the user is returned to the original screen, the screen before the menu bar was enabled. If the user selects OK, all the installed sensors are bump tested, starting with the first sensor.

The screen to alert the user to connect gas to the instrument is then shown.

Once the user presses Start, the gas should be applied.

If the user selects Skip, the bump for this particular sensor is not done. The instrument moves on to the next sensor in the list.

Figure 4-34. User Alert Screen (Apply Bump Gas)

If the user selects Start, the bump test is started for this sensor. The sensor must reach a gas reading of 50% or greater (user selectable in configuration menu) of the applied gas (calibration) concentration within 110 seconds to pass (This time is normally only 90 seconds but since the instrument doesn’t ‘know’ when the gas has been applied to start the timer, the default allows an extra 20 seconds). Once the sensor has done so, the word “pass” is displayed for 3 seconds before the instrument moves on to the next sensor.

Figure 4-35. Status and Results Screen for Bump Test Option



After all the sensors installed in the instrument have been bump tested, a result screen is shown. The user must acknowledge this screen to continue, by selecting the OK button.

If all the sensors have passed the bump test, the instrument goes into NRS.

If any sensor failed the bump test, after viewing and acknowledging the results, the instrument asks the user to continue, or calibrate the failing sensor(s).

Figure 4-36. Sample Results Screen for Bump

Test Option

Figure 4-37. Calibration Confirmation and Warning Screens After Failed Bump Test

If the user selects the Cancel button, the sensor is not calibrated and the instrument moves on to the next sensor in the list. If the user selects OK, the failing sensor is calibrated. The remove gas screen is shown for 10 seconds so that the user can remove the calibration cup so that the sensors are exposed to fresh air before the zero.

If there is more than one sensor that failed the bump test, they are calibrated in order (top row left to right, bottom row left to right on the Normal Readings screen), one at a time—each time prompting the user to choose whether to calibrate the sensor or not.

4.4.4. Peaks Under the main menu [Sensor] option, there is a [Peaks] menu option. The maximum gas reading (for toxic, LEL, IR and PID sensors) and the minimum gas reading (for O2 sensors) for each installed sensor is displayed.

If the [Peaks] option is selected, the instrument displays the peak reading for each sensor installed, except for oxygen, which shows the lowest reading.

iBrid Multi-Gas Sensor Configuration Menus


CHAPTER 5: CONFIGURATION MENUS

5.1. Overview Chapters 5, 6, and 7 detail menus that are password protected and require a user-defined code to gain access. These menus are collectively referred to as the “Configuration/Administration Menus,” but actually consist of 3 distinct protected areas:

• The Configuration Menu (Chapter 5) • The Sensor Menu (Chapter 6) • The Datalog Menu (Chapter 7).

These are similar to the earlier menus, but these menus provide a deeper layer of access for detailed operational configuration of the device. As such, the settings presented in these three chapters should only be adjusted by experienced personnel, as inadvertent or accidental changes to these settings could cause the alter the devices operation significantly. To prevent inadvertent or accidental changes to these critical parameters, these settings, which are collectively referred to as the “Configuration/Administration Menus,” are password protected.

5.2. Admin Options of the Admin menu include the following:

• Password • Clock • Language • Company • Defaults

These menu options are explained in the sections that follow.

5.2.1. Password From the normal operation menu [View] [Config], the user enters the password to get to the Configuration Menus, if a password has been set. If the password is still the default of nothing, no password protection is set.

The [Password] menu option allows the user to change the instrument password.

The [Password] screen is used to enter a password for verification, as well as changing the current password.

Passwords is a minimum of three (3) characters and a maximum of ten (10).

iBrid Multi-Gas Sensor Maintenance


CHAPTER 8: MAINTENANCE

8.1. Introduction The iBrid multi-gas sensor requires basic maintenance in order to provide years of reliable service. Maintenance topics are listed and explained below.

8.2. Charging the Battery The iBrid operates using internal rechargeable batteries that are not user-accessible. However, they must be recharged when their power level gets low. It is recommended that the iBrid should be fully charged prior to each day’s (or shift’s) use.

NOTE: The iBrid battery is charged before it leaves the factory, but should be fully recharged prior to use.

To charge the battery, follow the steps listed below:

1. Insert the power cord of the charger into an appropriate wall outlet.

2. Place the instrument in a Charger or DataLink charger (shown below).

3. Note that the LCD on the iBrid should show that the iBrid is charging.

4. Wait approximately 8-10 hours for the iBrid to be fully charged.

Figure 8-1. The MX6 iBrid Chargers (Charger and Combination Charger/DataLink)

Figure 8-2. Battery Charging Screens

If a Datalink or DS2 is communicating with the instrument, the blue icon in the lower left corner is displayed.

Maintenance iBrid Multi-Gas Sensor


8.3. Sensor Calibration and Zeroing In order to provide accurate gas monitoring, the sensors in the iBrid must be calibrated and zeroed on a regular basis. These processes for calibrating and zeroing are detailed earlier in this manual.

Gas detection instruments are potentially life-saving devices. Recognizing this fact, Industrial Scientific Corporation recommends that a functional (“bump”) test be performed on every instrument prior to each day’s use. A functional test is defined as a brief exposure of the monitor to a concentration of gas(es) in excess of the lowest alarm setpoint for each sensor for the purpose of verifying sensor and alarm operation and is not intended to be a measure of the accuracy of the instrument.

Industrial Scientific further recommends that a full instrument calibration be performed using a certified concentration(s) of Industrial Scientific branded calibration gas(es) monthly to ensure maximum accuracy. Use of calibration gases from manufacturers other than Industrial Scientific may void product warranties and limit liability claims against the manufacturer.

If an instrument fails to operate properly following any functional “bump” test, a full calibration should be performed prior to use.

8.4. Replacing the Batteries Though the iBrid should provide years of monitoring service, the rechargeable batteries may not continue to hold a charge forever. If over time, the iBrid shows signs that the batteries are no longer properly recharging, contact Industrial Scientific for information on battery replacement.

IMPORTANT: Be sure to turn off the instrument before (1) servicing the unit or (2) replacing the battery.

IMPORTANT: Battery contacts are exposed on battery packs when they are removed from the instrument. Do not touch the battery contacts and do not stack battery packs on top of each other.

8.5. Replacing the Filter Over time, the filter (located inside the iBrid chassis, beneath the sensor openings) may become dirty and negatively affect the performance of the device. The membrane filter is an integral part of the sensor cover. The membrane filter is replaced by replacing the complete sensor cover.

NOTE: Replacement filters can be purchased from Industrial Scientific.



Figure 8-3. Sensor Openings (Enlarged to Show Detail)

To replace the sensor filter:

• With the battery pack removed, open the iBrid chassis by removing the screw at the top of the chassis using a screwdriver.

• Remove the old sensor cover from the chassis • Replace the old sensor cover with a new one, being careful to align the new cover

properly. • Replace the chassis cover using the screws from the first step.

Filter replacement should be done in a clean environment free of dust and debris. Also, the device contains static-sensitive components, so proper electrostatic discharge (ESD) precautions must be ensured.

If you have any questions about changing the sensor filter, please contact Industrial Scientific.

8.6 Replacing the Sensors Sensors in the MX6 should be replaced after failed calibrations. Sensor replacement is designed to be very easy and performed in the field.

To replace the sensors in the MX6

• Remove the battery pack and sensor cover from the chassis as described above.

• Firmly grasp the sensor module you wish to replace and remove it from the chassis.

• Align the new according to the outline of the sensor board shown on the instrument chassis

• Firmly press the new sensor into place until the sensor connectors engage.

• Replace the sensor cover and battery pack.

Maintenance iBrid Multi-Gas Sensor


8.7 Replacing the Pump Filter If your MX6 instrument has the internal sampling pump module installed, it may be necessary to replace the sample pump filter in the event that it becomes dirty or clogged. The MX6 will indicate PUMP FAULT on the display when the filter is clogged and needs replaced.

To replace the pump filter

• Unscrew the threaded pump inlet cap from the top of the unit.

• Remove the sample filter taking note of the proper orientation.

• Insert the new filter into the pump chassis, making sure to orient the filter in the same direction as the old filter.

• Re-install the pump inlet cap on the top of the unit.
