Types of calibration
You can set the following types of calibration:
Table 6- 3 Types of calibration
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. However, the newly calculated calibration parameters of this leading measuring
range are transferred to all other measuring ranges. All measuring ranges can be adjusted
simultaneously in this way.
Sequence
Information on the sequence of a calibration/validation is available at: → Sequence of a
calibration/validation (Page 116).

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 by adjusting a sensitivity factor
accordingly. 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.
