Aeroqual AQM60 User Guide
Note 1: The recommended dilution ratio range is between 50 and 500
Note 2: If the cylinder contains calibration gas in a balance of Nitrogen, a minimum dilution ratio of
50 should be used
Gas lines in to AQM
The regulator provides gas into the AQM via 1/8 OD stainless steel
tube with a 1/8 compression fitting at the end of the tube to allow
connection to the regulator.
Regulators
The AirCal 8000 comes supplied with 2 two stage regulators. The
maximum input pressure allowed into the first stage is 3000 psi.
The inlet fitting is a ¼ FNPT. The regulator is also supplied with a
¼ FNPT to 5/8 x 18 thread fitting which will allow it to be attached
to many commercially available gas cylinders including the Calgaz
range.
The maximum outlet pressure from the second stage is 15 psi. The
outlet fitting from the regulator is a 1/8 FNPT thread fitting. The
regulator is supplied with a 1/8 FNPT to ¼ Swagelok compression
fitting.
Gas Connection
Screw the gas cylinder into the stainless steel regulator and adjust the pressure valve (screw in) until the
outlet pressure is 6 PSI.
4.5.4. Configuring the AirCal 8000 scheduler
Calibration can be configured to be carried out automatically at a set time for a chosen running period:
Define the composition of the cy
linders attached to the AirCal inlet ports by clicking “Setup”
“Calibration configuration” in the software.
When the calibration dialogue is first accessed there will be no information in the cells describing the
port configuration.
To configure the port click in the cell and enter the appropriate information.
To configure the run scheduler, right click inside the run scheduler dialogue box and select “add new
run
”.
A run may include up to 5 points including zero air which is defined as Port 0.
A maximum of 3 runs can be configured for automatic calibration.
The user will need to define the dilution ratio for Port 1 and 2 as well as the run time.
The schedule can then be selected from the drop down menu to configure the calibration run
frequency, day of week/month and start time.
Once all the parameters have been set click save then click read to ensure the run has been saved.
It is recommended to set the AQM60 logging frequency to 2 minutes if using the Auto Calibration. If
the logging period is 10 minutes, and the calibration point is set to run for 30 minutes then only three
points will be recorded for the calibration, and it is possible the correct response my not be recorded.
