Single calibration is only possible if the
"Total calibration" subfunction has been deactivated
in function 23.
All measuring ranges defined using function 41 appear in the display. The above function
screen is an example of the single calibration of four measuring ranges.
If you would like to calibrate range 3, press the corresponding softkey.
The setpoint and current actual value of the selected range then appear in the display:
21 Sp.cal. MR 3 O

Setpoint : 9999.00 vpm
Act.val. : 9901.00 vpm

When the actual value has stabilized, you can initiate the calibration process by pressing the
fourth softkey. The actual value is now made to agree with the setpoint.
If a calibration is carried out incorrectly (e.g. using the wrong calibration gas) repeat the
complete calibration procedure.
If the calibration is aborted because the calibration tolerance is too large, check your
calibration gas as well as for leaks in the analyzer (chapter 4.3.2). If the calibration gas is
OK, and if there are no leaks, try to carry out a basic calibration using function 26 (adjust
sensor). If the calibration tolerance is still too high, the sensor may be faulty.
Total calibration ("Measure" operating state required)
Total calibration is only possible if the
"Total calibration" subfunction has been activated
using function 23.
With a total calibration, you calibrate all measuring ranges together. Define the "leading"
measuring range in function 22. We recommend that you use the largest measuring range
for this.
The setpoint and current actual value of the "leading" measuring range appear in the display.
When the actual value has stabilized, you can initiate the calibration process by pressing the
fourth softkey. The actual value is now made to agree with the setpoint.
If a calibration is carried out incorrectly (e.g. using the wrong calibration gas) repeat the
complete calibration procedure.
