Attach the mains cable to the connector on the side of the indicator. The power switch is located next to he mains inlet.

Load cell connect as below( 9 pin D-sub connecter)

SECTION 4 KEY DESCRIPTIONS

0-9,

Numeric entry keys, used to manually enter a value for tare weights, unit weight, and sample size.

CE , CUsed to clear the unit weight or an erroneous entry.

Zero

Set the zero point for all subsequent weighing. The display shows zero.

Tare

Tares the scale. Stores the current weight in memory as a tare value, subtracts the tare value from the weight and shows the results. This is the net weight. Entering a value using the keypad will store that value as the tare value.

M+

Add the current count to the accumulator. Up to 99 values or full capacity of the weight display can be added.In the weighing status, the value of weight would be added.

In the counting status, the value of count(PCS) would be added.

And also, to print the results to a PC or printer using the optional RS-232 interface when the current count to the accumulator successfully.Mode

Shift the status of weighing ,sample and counting.

Smpl Used to sample the unit weight ot ensure the number of items when sampling.

Unit Wt

Used to enter the weight of a sample manually.

Pn or or AlrTo set the low and upper limit for the number of items counted. When this low or upper the limit have been set, the scale will sound the beeper. And also, press this key to stop the alarm sound.

G/NTo shift the gross weight and the net weight.

SECTION 5 DISPLAYS

The LCD display will show a value and a unit to the right of the digits.

In addition there are labels for TARE, GROSS weight, Zero and for Low battery

SECTION 6 OPERATION 6.1 Zeroing The Display

You can press the ZERO/ENTER key at any time to set the zero point from which all other weighing and counting is measured, within 4% of power up zero. This will usually only be necessary when the platform is empty. When the zero point is obtained the display will show the indicator for zero.

The scale has an automatic rezeroing function to account for minor drifting or accumulation of material on the platform. However you may need to press the ZERO/ENTER key to rezero the scale if small amounts of weight are shown when the platform is empty.

6.2 Normal tare

Zero the scale by pressing the ZERO key if necessary. The zero indicator will be on.

Place a container on the platform, a value for its weight will be displayed.

Press the TARE key to tare the scale. The weight that was displayed is stored as the tare value and that value is subtracted from the display, leaving zero on the display. The "Net" indicator will be on. As product is added only the weight of the product will be shown. The scale could be tared a second time if another type of product was to be added to the first one. Again only the weight that is added after taring will be displayed.

When the container is removed a negative value will be shown. If the scale was tared just before removing the container this value is the gross weight of the container plus all product that was removed. The zero indicator will also be on because the platform is back to the same condition it was when the ZERO key was last pressed.

6.3 Predictable tare

This method allows you to enter a value for the tare weight from the keypad. This is useful if all containers are the same or if the container is already full but the net weight is required and the tare weight of the container is known.

Remove all weight from the platform, press the ZERO key to zero the display.

Enter the value for the Tare weight using the keypad, press TARE to store the tare value. The weight will show a negative value equal to the tare.

Place the container on the platform.

The display will then show the weight of the container minus the tare weight. Then when the full container is put on the platform the tare value will be subtracted from the gross weight displaying only the net weight of the contents.

If the value input is not consistent with the increment of the scale the scale will round the tare value to the nearest value possible. For example if a tare value of 10.3g is entered onto the 6Kg/0.5g scale then the display will show -10.5g.

6.4 Weighing a sample

To determine the weight of a sample first tare the empty container then place the sample in the container. the display will show the weight and the units of weight currently in use.

6.5 Gross/Net shift

Press G/N key directly to shift the gross weight and net weight.

SECTION 7 PARTS COUNTING 7.1 Setting Unit WeightAt first, you should enter the sampling mosde using the Mode key.

In order to do parts counting it is necessary to know the average weight of the items to be counted. This can be done by weighing a known number of the items and letting the scale determine the average unit weight or by manually inputting a known weight using the keypad.

Weighing a sample to determine the Unit Weight

To determine the average weight of the items to be counted it will be necessary to place a known quantity of the items on the scale and then to key in the quantity being weighed.

The scale will then divide the total weight by the number of samples and display the average unit weight.

Zero the scale by pressing the ZERO key if necessary. If a container is to be used, place the container on the scale and tare as discussed earlier.

Place a known quantity of items on the scale. After the weight display is stable enter the quantity of items using the numeric keys followed by SMPL key. After several seconds, the computed average weight will be shown on the display.

As more items are added to the scale, the quantity will increase.

If the scale is not stable, the calculation will not be completed. If the weight is below zero, the quantity display will show negative count.

7.2 Entering a Known Unit Weight

At first, you should enter the sampling mosde using the Mode key.

If the unit weight is already known then it is possible to enter that value using the keypad.

Enter the value of the unit weight using the numeric keys followed by pressing the SAMP key. The display will show the value as it was entered.

The sample is then added to the scale and the weight will be displayed as well as the quantity based upon the unit weight.

7.3 Parts Counting

After the unit weight has been determined or entered it is possible to use the scale for parts counting. The scale can be tared to account for package weight as discussed in an earlier section.

After the scale is tared then the items to be counted are added and the display will show the number of items computed using the weight and the unit weight.

It is possible to increase the accuracy of the unit weight at any time during the counting process by entering the count displayed then pressing the SMPL key. You must be certain the quantity displayed matches the quantity on the scale before pressing the key. The unit weight will be adjusted based upon a larger sample quantity. This will give greater accuracy when counting larger sample sizes.

7.4 Automatic Part Weight Updates

The scales will automatically update the unit weight when a sample equal to less than the sample already on the platform is added. A beep will be heard when the value is updated. It is wise to check the quantity is correct when the unit weight has been updated automatically.

This feature is turned off as soon as the number of items added exceeds the count used as a sample.

7.5 Count Preset or Check-weighing

Check-weighing (Count Pre-setting) is a procedure to cause an alarm to sound when the number of items counted on the scale meets or exceeds a number stored in memory by using the Alr key.

The stored value is entered from the keyboard. Enter the numeric value to be stored using the numeric keys. Then press the Alr key to store the value.

To clear the value from memory and thereby turn off the check-weighing feature, enter the value "0" into the memory.

7.6 Manually Accumulated Total

The values (weight and count) shown on the display can be added to the values in the accumulator by pressing the M+ key. The display will show the total accumulated count and and the number of times items have been added to the accumulation memory. The values will be displayed for 2 seconds before returning to normal. and also, when accumulate successfully, the values will be print out from the RS-232 interface.

The scale must return to zero or a negative number before another sample can be added to the memory.

More product can then be added and the M+ key pressed again. This can continue for up to 99 entries, or until the capacity weight display is exceeded.

7.7 Automatic Accumulated Totals

The scale can be set to automatically accumulate totals when a weight is placed on the scale. This eliminates the need to press the M+ key to store values into memory. However the M+ key is still active and can be pressed to store the values immediately. In this case the values will not be stored when the scale returns to zero.And also, when accumulate successfully, the values will be print out from the RS-232 interface.

See the PARAMETERS Section for details of how to enable Automatic Accumulation.SECTION 8 BATTERY OPERATION

The scales can be operated from the battery if desired. The battery life is approximately 100 hours.

When the battery needs charging the arrow above the low battery symbol under the weight display will turn on. The battery should be charged as soon as the arrow above the symbol is on. The scale will still operate for about 10 hours after which it will automatically switch off to protect the battery.

To charge the battery simply plug into the mains power. The scale does not need to be turned on.

The battery should be charged for 12 hours for full capacity.

Just under the quantity display is an LED to indicate the status of battery charging. When the scale is plugged into the mains power the internal battery will be charged. If the LED is green the battery has a full charge. If it is Red the battery is nearly discharged and yellow indicates the battery is being charged.

As the battery is used it may fail to hold a full charge. If the battery life becomes unacceptable then contact your distributor .

SECTION 9 PARAMETERS The scale has 10 parameters that can be set by the user plus a method of entering the calibration section.

Turn off the indicator, press the TARE key when selfchecking. Then a password will be required, the default value is 9999.

Then the display will show the first function, "F0 CAL".

Pressing the Unit Wt key will cycle through the other functions.

Pressing TARE key will allow you to set the function. It may be necessary to use the M+ key to move the active digit left and then using the Unit Wt key to increment a digit, followed by the TARE key to enter the value. Use the ZERO key to leave a parameter unchanged.

For example when the display shows F1 inc press the TARE key to begin.

The display will show inc 1, press the TARE key to set the TARE, or press the Unit Wt key to select the next parameter,

When all digits have been set press the TARE key to store the value. The display will go back to the parameter just set, press the ZERO key to return to weighing.

SECTION 11 CALIBRATION The scale can be calibrated using the following procedure. For a more detailed method of calibrating the scale it will be necessary to enter the secure Programming Menu.

The indicator calibrates using metric weights and the T-2000M indicator can calibrate using either metric or pound weights, depending on the weighing unit in use before calibration. The display will show either "kg" or "lb" to identify the weights expected.

PROCEDURE

Turn the power off.

Turn the power back on, during the counting from 9 to 0 press the TARE key. Then a password will be required, the default value is 9999.

The display will show "CAL " for a few seconds. While it is showing "CAL " press the TARE key to enter the Calibration section. The display will show "unLoAd".Remove any weight from the platform. Press the TARE key.

The display will show "LoAd". Place the calibration weight on the scale. Press the TARE key.

The display will show the last calibration weight used. If this is correct you can continue by pressing the TARE key. If it is not correct use the M+ key and the Unit weight key to change the calibration weight value. When it is correct press the TARE key.

If the calibration is acceptable and then return to normal. If an error message is shown try calibration again as a disturbance may have prevented a successful calibration.

If the problem persist then contact Taiwan scale or your dealer.

After calibration the scale should be checked to verify the calibration and linearity is correct. If necessary repeat calibration, especially be certain the scale is stable before accepting any weight.
