Aeroqual AQM60 User Guide
The calibration log will record the port specification and the data from all of the configured sensors including
the port which is being used and the dilution ratio. In the example shown above Port 1 has been opened and
the AirCal is applying a dilution ratio of 10. The flow rate from the MFM and the MFC is recorded to allow the
user to confirm that the correct dilution ration has been applied.
4.5.6. Performing a Manual Calibration
Zero Check (Port 0)

Select
“Tools”

“Turn on Zero Scrubber” to initiate the zero air check

Readings will be taken every minute

the MFM measurement (±5ml/min)

To stop the zero check select
“Tools”  “Stop Check”
Span Check

Select “Tools”  “Turn on Span Check” to initiate the span check

The port and dilution ratio need to be defined
Note: In this example, if port 1 is configured with CO (250 ppm) then the AirCal will deliver 25 ppm
CO assuming the correct cylinder has been defined in the calibration configuration dialogue (Section
4.5.4.)

Readings will be taken every minute

Allow for the sample gas to stabilise (15 minutes). Be aware that there may be some fluctuation in
