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.

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.

The parameterized test gas concentration is displayed. If the set point is altered
here, the parameterized test gas concentration is overwritten.
