4.3 Commissioning and operation
Span adjustment
The setpoint should be as close as possible to the full-scale value (at least 70% of the
respective span). Connect the corresponding calibration gas for the span adjustment. The
setpoint is also entered using function 22.

General information on calibration

Note
Calibration is only possible when the device is in the "Measure" operating state.
Zero point
The zero point is calibrated using function 20. The device displays both the setpoint and
actual value.
Note
Note that this function can only be activated if AUTOCAL (function 24) is deactivated.
Single / total calibration
A single or total calibration is selected using function 23.
Single calibration means that each measuring range is calibrated using a separate
calibration gas.
During a total calibration, the measuring ranges defined using function 41 are calibrated
together.
Sensitivity
Select function 21 and carry out the desired calibration. Note that this function can only be
activated if AUTOCAL (function 24) is deactivated. If the total calibration was activated
previously, all measuring ranges are then calibrated.
If you have selected single calibration (total calibration deactivated), repeat the calibration
procedure for each measuring range individually with the corresponding calibration gases.
(In function 22, a calibration gas must be entered for every measuring range!)
