Calibrating the gas analyzer
Gas analyzer manual calibration
NOTES
Calibration should only be started after the warm-up phase.
A manual zero calibration must always be carried out before a manual span
calibration.
Gas analyzer manual calibration
1 Select the Manual Calibration menu:
MENU
→ Calibrate → Manual Calibration
2 For single calibration: Select Component and Measurement Range.
Zero calibration:
3 Select Zero Gas.
4 Turn on the zero gas supply.
5 If necessary, change the test gas concentration

shown, ENTER.
6 When the sample value indication stabilizes, initiate zero calibration
with ENTER.
7 Accept the calibration result with ENTER
or REPEAT
2
calibration (back to step 5)
or reject calibration with Back (back to step 6)
or reject calibration with Meas (back to measurement value readout).
Span calibration:
8 Select Span Gas.
9 Turn on the span gas supply.
10 If necessary, change the test gas concentration

11 When the sample value indication stabilizes, initiate span calibration
with ENTER.
12 Accept the calibration result with ENTER

4
calibration (back to step 10)
or reject calibration with Back (back to step 11)
or reject calibration with Meas (back to measurement value readout).
13 For single calibration, repeat steps 2 to 12 for other components and
measurement ranges.
1
The parameterized test gas concentration is displayed. If the set point is altered
here, the parameterized test gas concentration is overwritten.
2
A calibration may have to be repeated if the measured value is not stable after initi-
ation of the calibration. The repeated calibration is based on the measured value
obtained in the preceding calibration.
3
The parameterized test gas concentration is displayed. If the set point is altered
here, the parameterized test gas concentration is overwritten.
4
A calibration may have to be repeated if the measured value is not stable after initi-
ation of the calibration. The repeated calibration is based on the measured value
obtained in the preceding calibration.
