Caution.
Set up the test gas and reference air supplies before running a calibration –
see IM/AZ20P-EN.
Procedure
Calibration Type and Description
1-Pt AutoCal
Single-point automatic calibration of Calibration Offset
The values of the two test gases are compared and an offset
calibration is performed using whichever test gas is closest to air
(20.95 %).
If the values of the two test gases are equal, test gas 1 is used.
2-Pt AutoCal
Two-point automatic calibration of Calibration Offset and Calibration Factor
Performs slope and offset calibration using both test gases.
Manual Cal – Offset
Single-point manual calibration of Calibration Offset
The values of the two test gases are compared and an offset
calibration is performed using whichever test gas is closest to air
(20.95 %).
If the values of the two test gases are equal, test gas 1 is used.
Manual Cal – Factor
Single-point manual calibration of Calibration Factor
The values of the two test gases are compared and a factor
calibration is performed using whichever test gas is furthest from air.
If the values of the two test gases are equal, test gas 2 is used.
Manual Cal – 2-Pt
Two-point manual calibration of Calibration Offset & Calibration Factor
Performs slope and offset calibration using both test gases.
