Zero scrubber solenoid switching OK
With the AQM c
onnected to the PC, go to “Tools”
“Turn Zero Scrubber ON” and confirm there is a
click from the solenoid in the Gas Treatment Module when the zero scrubber is turned on.
Zero scrubber efficiency OK
Allow the AQM to sample air containing VOC, CO or O3 gas and confirm that when the zero
scrubber is activated the readings decrease close to zero.
Modem Communication OK (Optional)
Configure the modem by following the instructions in the User Guide (Section 3.3) or the modem
manufacturer’s instructions.
Connect the Modem (GSM, RF etc.) to the serial port on the AQM Control Module and power up
using the 12 VDC power socket on the side of the Control Module.
Establish a connection to the AQM via the PC software and confirm communication is OK.
2.3.3. System Values
Enclosure temperature
The AQM internal temperature is recorded on the SD card as ITemp. To check if the thermal management
system is functioning correctly, plot ITemp vs. Time for a period of several hours and ensure the internal
temperature is stable (±1
o
C) and matches the ITemp value stated in the AQM logbook.
AQM inlet flow
Using a volumetric flow meter record the flow on the AQM sample inlet. Check it is the same as the inlet flow
stated in the AQM logbook.
Module flows
Use a volumetric flow meter to record the flow on the inlet port of the gas modules. These should match
those of the Logbook. If the flow rate does not match the rate written on the module adjust the flow using the
AQM GTM bypass valve and/or check for leaks. (See Section 7.3.2.)
Particle Monitor/Profiler flow
If a particle monitor or profiler is present, use a volumetric flow meter to
record the flow on the external inlet. Remove the TSP head and connect
the flow meter to the top of the sharp cut cyclone. The inlet flow can be
adjusted via the bleed screw on the purge line. Afterwards replace the
inlet components with care making sure there is no leak.
Note 1: Particle Monitor inlet flow rate should be 2LPM
Note 2: Profiler inlet flow rate should be 1LPM
2.3.4. Zero and Span Checks for Gas Modules
Refer to Section 4 on how to carry out zero and span checks and calibration.
