8.7 [1.5] Calibration
Types of calibration
You can set the following types of calibration:
Table 8-1 Types of calibration ("Customer calibrations")
Calibration
1-point zero gas calibration
1-point span gas calibration
2-point calibration
Scope/reference
Single calibration
Calibrations can be run as single or total calibrations. Only the selected measuring range is
calibrated in a single calibration, while the calibration parameters of all other measuring ranges
are not affected.
Total calibration
In a total calibration, at first the selected measuring range is calibrated as with single calibration.
But the newly calculated calibration parameters of this leading measuring range are converted
for all other measuring ranges. This means all measuring ranges can be calibrated with the
same calibration parameters.

Description
This calibration eliminates drifts in the zero point. The setpoint corresponds to the
actual value in the zero point.
This calibration eliminates drifts in the span point. The setpoint corresponds to the
actual value in the span point.
In this type of calibration, zero gas validation and span gas calibration take place
successively.
