You will need to bring:
Gas inlet filters
Gas dilution calibrator / Zero air generator (combined or separate ozone generator)
Gas cylinders with suitable gas concentrations
Flow meter: Aeroqual R7
Before you begin
NOTE: Both the AirCal 1000 and the Ozone calibrator take time to warm up and become stable.
Turn on the AirCal 1000 and switch on the pump override switch on the back panel for at least
30 mins before staring the calibration.
Turn on the Ozone generator and set it to deliver 0.1 ppm Ozone for at least 30 mins before
starting the calibration, this allow time for the lamp in the ozone generator to stabilise at 0.1
ppm.
The Calibration screen in the Calibration and Service App in the Aeroqual software is where you will
perform the calibration and change any monitor settings.
Figure 7-3 The main calibration screen is where the average and standard deviation can be read. This is
also where the gain and offset can be read and set.
Figure 7-4 The Manual Entry section of the Calibration and Service App is where the gain and offset and
the a value on the NO2 module is set.
NOTE: The connection to the
monitor
inlet differs depending on whether you are using the AirCal
1000 or the Ozone calibrator. See images below for how the connections differ.
