8. Calibration post-checks

Follow these post-calibration checks and record the results in table 9 in your calibration form.

Disconnect your calibration equipment.

Disconnect the gas cylinders and safely remove the gas regulators.

Pack away all the calibration gear.

Check the gas inlet is secure and do a final inlet flow check.

Replace the mesh inlet and cap.

Lock the monitor's door.

Secure the site (if necessary).

Exit service mode.

Make sure your calibration form is complete.

Schedule the next calibration.

Make sure the journal in Aeroqual Connect / Aeroqual Cloud contains all the details of the calibration.

The journal automatically records any changes you apply to the offset or gain.

You must log when you applied zero air as this is not automatically recorded, unless you are using the AirCal 8000.

We recommended you record details about cylinder concentrations.

Record which span points you are using and when you started the span gas flowing.
