1 Installation
To run the LabView software, some programs have to be installed first, incorporated in
the
Installation package labview XEN-5320 v3.0 software:
LVRTE2014_f1Patchstd.exe
NI_VISA_5.2.0-runtime.exe
atmel_devices_cdc.inf
XEN-5320-v3.0.exe (and 2 supporting files)
The first two programs have to be installed, and the computer has to be restarted. The
third program is the driver for the USB port, and has to be installed via the configuration
screen of the computer. This is done as follows:
First plug in the XEN-5320 device to a USB port of the computer.
Then in the configuration screen go to the device manager and update the driver of
the XEN-5320 device. During installation Windows will give the following warning:
“Windows can’t verify the publisher of this driver software”. Press “install the driver
anyway” to continue the installation. This driver will make a virtual COM port for
each connected XEN-5320 device.
Then the Polling program will run.
2 Versions
The previous versions of the LabView software were version 1.4 for firmware versions
1.4; version 2.0 for firmware version 2.0.
Currently the valid LabView version is 3.0 for XEN-5320 firmware version 3.0.

3 The Connection Settings Page
When the Polling program opens, the Connection Settings page comes up
automatically, see Fig. 1.
In the Connection Settings page, the file path for filing the measurement data has to be
given.
Then, 1 or more COM ports have to be chosen to select the device to be recorded
when using the USB connection, or an IP address has to be chosen if the WIFI
connection is used.
WIFI and USB can be used intermixed.
By clicking the pull-down arrow at the right of the IP address or COM port selector, a
choice is given of available IP addresses or COM ports, and also a refresh command
becomes available to refresh the available COM ports. When using different IP
addresses than the one available in the list, it is also possible to type in a different IP
address manually. By pressing the button Fill in standard IP addresses, the standard IP
addresses for all 25 devices are filled in automatically, which can be convenient when
using a lot of devices by WIFI. The device ID field is updated only when the WIFI/USB
selection, IP address or COM port is changed. The button Refresh Device ID can be
used to update the device ID fields.
All ports are read out in parallel.
The Enable button should be activated (indicated by the green light in the button) to
actually measure the device to its left.
The Start button at the bottom of the Settings page (and all other pages) starts the
measurements, indicated by a green Running light.
The Stop button stops the measurements, this can take up to several seconds.
The Quit button exits the program when not running, the X at the top right of the screen
exits anyway.
The Delay window allows to slow up the measurements if they go to rapid. The Delay
is in seconds.
In the Select directory for saving measurement data window the file name for
storing the data shown the Reception History can be given by the user. Each
measurement is immediately stored in the file, there is no need for any further action to
save data. A file for each sensor is made. For the first measurement of the day, a new
file is created. Subsequent measurements on the same day are appended to the
existing file.

5 The Measurement Mode page
Fig. 3 shows the measurement mode page. On this page the curve used to calculate
the output signal (% and ppm) is chosen. Also chosen is the measurement speed:
Standard (3.3 Hz) or Fast (≈40 Hz).
If H2 is chosen, a look-up table will be used to convert the change in transfer (the
deviation of the Corrected Transfer from unity) into the output signal.
For HE the 2nd order polynomial curve for helium is used.
For GEN the change in corrected transfer is simply displayed.
For VAC the change is converted to pressure using a formula that describes the output
of the sensor as function of vacuum pressure. The absolute pressure is given in Pa.
When the Custom Curve is chosen, a user provided 23-point look up Table will be used
to calculate the output (%) signal.

Burst and TAU can also be displayed as Measurement Mode, but a separate LabView
program (Burst Tau v3.0) is used to measure in these ultrafast modes (80-750 Hz). If
one of these Modes is displayed, change into one of the other modes first to perform
valid measurements.
Be sure to stop the measurement first, before checking or changing the measurement
mode. If there is still a measurement running (green light below Running), then nothing
will happen.
6 Set output zero Page
The Set output zero Page (see Fig. 4) allows zeroing of the device. The zeroing data
are stored in the memory of the XEN-5320, and zeroing can be carried out when so
desired. Zeroing starts by pushing the Start set output zero button (after stopping the
measurements). The zeroing takes a number of seconds, the busy light is flashing
green and yellow.

7 Gain Calibration Page
The Gain Calibration page allows for calibration of the 100% value for the helium or
hydrogen signal in the helium or hydrogen measurement modes. The measurements
should be stopped.
This action can be performed either via WIFI or USB.
In HE measurement mode, 100% helium should be present around the sensor head, in
H2 mode 100% hydrogen should be present. When the Start gain calibration button
is pushed, the program will perform a measurement, calculate the output and calculate
a gain factor to adjust the output to 100%. If the adjustment that is required is more
than a few percent, the error light will shine and a gain factor of unity is returned (see
Fig. 5).
The gain factor is stored in the EPROM of the XEN-5320.

11 Alarm Page
The Alarm page shows the cumulative codes of a selected group of warnings and
errors, calculated by the LabView program, see Fig. 11. The code is stored at each
measurement, and warns if anything is out of the ordinary or even wrong. For each
sensor a light will shine on the Connection Setup Page to indicate for which sensor the
alarm is going off. On the sensor’s Reception History Page, or in the file, the codes can
then be found and checked. The higher the code, the more serious the problem.

12 The Reception History Page
12.1 The displayed data
On the Reception history page, the measurement data are shown as numbers, see Fig.
12. There is a Reception history page for each sensor, up to 25 sensors. At the top of
each page, the Sensor IDentification is shown, the Firmware version of the sensor,
the Measurement mode, i.e., the conversion curve used to calculate the output in %.
This can be altered on the Measurement mode page. And finally the Gain is shown,
the gain can be calibrated on the Gain Calibration page. The output values are
multiplied with the gain to get a 100% output when 100% of the second gas type is
present. For instance, for an air-helium curve, gain calibration is performed in 100%
helium. The gain factor is calculated to get the displayed output also to 100%. If the
calculated value deviates too much (more than a few percent), for instance, when a
wrong gas mixture is present, the gain is set to unity instead.

It can be that your computer shows only zeros after the decimal separator, if this
separator is a comma. This separator should be changed into a point(.), and then,
correct trailing digits will appear. This can be done in the Country & Language part of
the configuration screen of your PC.
Explanation of the columns.
Iteration is the number of the measurement, this is counted per device and starts at 0.
The iteration restarts at 0 after a stop and (re)start of the measurements.
Time is the computer time of the measurement. It is given in increments of 10 ms.
However, when importing the data into EXCEL, the time is displayed only in full
seconds, unless the notation is changed into an adjusted notation (go to cell properties,
and use an adjusted notation as u:mm:ss.00).
Output in % is the deviation of the corrected transfer with respect to the calibration
transfer.
In case the Measurement mode is H2 for hydrogen, the output is given as % H2
concentration. This mode measures in the electronics’ 50-mV measurement range.
In case the Measurement mode is He for helium, the output is given as %helium. This
mode measures in the electronics’ 50-mV measurement range.
In case the Measurement mode is GEN, a general output is given as % of the
difference between the calibration transfer and the corrected transfer. This mode
measures in the electronics’ 200-mV measurement range.
In case the Measurement mode is VAC, the output is converted into an air vacuum
pressure in Pa. This mode measures in the electronics’ 200-mV measurement range.
Transfer in V/W (output voltage of the thermocouple sensing element divided by the
heater power) is what has been measured.
Pt100 in ºC is the temperature measured with a Pt100 element in the thermal
conductivity sensing-element housing.
Tsens in ºC is the temperature measured with the Sensirion humidity sensor.
RH (Relative Humidity in %) is the RH measured by the Sensirion RH sensor.
AH shows the absolute humidity pressure in kPa. It equals the RH times the saturation
water vapor pressure at Tsens.

Corr_transfer, the corrected transfer gives the nominal transfer (but not in V/W) as
calculated after correcting for the differences between the temperature and humidity
during calibration and during measurement. The remaining difference from unity is then
ascribed to the parameter to be measured.
Utp is the output voltage of the thermopile measuring the temperature elevation of the
heater element.
Ih in mA is the current through the heater element on the sensing element’s
membrane.
Uh in mV is the voltage across the heater element on the sensing element’s
membrane.
Ph in mW, the multiplication of Ih and Uh is the power dissipated in the membrane.
The Thermocouple voltage Utp divided by the Heater Power Ph gives the measured
Transfer.
USyst in V gives the power supply voltage of the XEN-5320 after stabilization. This
should normally read as about 3.3 V.
UBat in V gives the LI-ion battery voltage. It will be 4.2 V when the sensor is connected
through USB. Then the system is running on USB power and the Li-ion battery is
recharging.
If the battery is full, the yellow LED next to the USB connector will light. If the battery is
charging, the red LED next to the yellow LED will light up.
The green LED next to the red LED will flash if the sensor is operational.
If the system is operating on the battery, the Ubat will be in the range of 4.1~3.6 V.
Bat (%) shows the battery charge in %
Alarm shows a code for a selected number of warnings and errors. Se the Alarm
Chap. for the codes.
12.2 The filed data
All data are stored in a text file, with a name starting with the date (yyyy-mm-dd),
followed by the device name. If no file for the current date exists, a new file will be
made. Otherwise, the data are appended to the existing file.

For each device and day, a new file is made. The file starts with some general data on
the device, with subsequently all the measurement data. If the measurement is stopped
and then started again, the header data are repeated.
The header resembles the data shown in Fig. 13 below (with some long numbers
reduced in length):
Figure 13: The Filed data.
The Device ID is a unique coding for each XEN-5320.
The Factory Device ID is the name given to the device by the manufacturer.
The Firmware is the version of the microcontroller program.
The Measurement mode is explained above.
The Speed is the measurement speed.
The Sensitivity is a nominal multiplication factor to convert a change in transfer into a change in measurement parameter. For low hydrogen concentrations the factor of -1.93 %/% that is shown is an indication that a 1% increase in hydrogen concentration leads to a 1.93% decrease in corrected transfer level. For hydrogen a full-range a look-up Table is used.
For He (helium), a polynomial is used, at low helium concentrations the sensitivity is of the order of -1.1 %/%. For Gen (General) firmware unity sensitivity is used. For VAC the output is converted into a vacuum pressure in Pa. TC Transfer is the correction factor in the firmware for temperature changes. AH1-AH2-AH3 are the coefficients of the 3rd power polynomial curve in the firmware to correct for changes in (absolute) humidity. Y_AH_Cal (-) is the correction factor used for humidity during calibration. TF_Cal (V/W) is the transfer during calibration. Temp_Cal (ºC) is the temperature during calibration. The Gain is the factor by which the output is multiplied to get a 100% output value for 100% second gas. These three factors give the XEN-5320 measurement data during calibration. It is possible to update these calibration data by performing a new calibration using the Calibration Page. These data are used, together with subsequent temperature and humidity measurement to first calculate the corrected transfer at the subsequent measurement. Then difference between the corrected and actually measured transfer is used to calculate the output signal, either using the Sensitivity, or with a more complicated formula or look-up Table. Then the same data are given as displayed in the reception page.

13 The Graphs Page
On the Graphs Page, one of all the parameters that are shown in the reception can be
displayed against the iteration number. Time cannot be displayed.
There is one display per sensor, 5 sensors per sub-page. There are 5 sub-pages to
display all 25 sensors.
Alternatively, up to 5 parameters of sensor #1 can be displayed on one page.
Fig. 14. shows several data of sensor 01BC01: output (%), Utp (mV), Corr transfer (-),
Tsens ( ºC) and AH (kPa), for some 670 measurements. The data refresh time is about
25 ms for the Fast measurement speed used here. The graph shows the effect of
breathing in and out over the XEN-5320. An average Absolute Humidity (AH) of about
4 kPa is attained, where the Maximum Saturation pressure of water vapor at 37 ºC is 6
kPa.

14 Communication commands
For those who want to organize their own communication between XEN-5320 and
control device (computer, lap top, smart phone?), the communication commands can
be found in the XEN-5320 Version 3.0 data sheet.
15 Trouble shooting
The measurement data show a lot of zero’s
instead of real data.
It can be that your computer shows only zeros
after the decimal separator, if this separator is a
comma. This separator should be changed into a
point(.), and then, correct trailing digits will appear.
This can be done in the Country & Language part
of the configuration screen of your PC.
The time data are wrong when importing the
measurement file into EXCEL.
Be sure to define the time data column as
u:mm:ss.00 in the cell properties, adjusted
format.
When importing the measurement data into
EXCEL they are of an incorrect magnitude.
This is a point/comma settings result. When
importing the data in EXCEL, use the advanced
settings to exchange the designation of a point
and a comma.
Communication of the LabView program with the
WIFI router is not working.
Be sure to have the settings of the computer and
the router exactly as explained in the WIFI
chapter.
The communication with the WIFI devices is not
working.
Be sure to have the settings of the devices
corresponding to the settings of the router.
Commands in the Calibration and Settings Page
do not work.
Stop the measurement before performing these
actions.
