Calibration Type and Description
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.
Two-point automatic calibration of Calibration Offset and Calibration Factor

Performs slope and offset calibration using both test gases.
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.
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.
Two-point manual calibration of Calibration Offset & Calibration Factor

Performs slope and offset calibration using both test gases.
