2. Start Recording
■ Yes: Launches the recording of calibration measurements for the selected
detectors. From this moment onwards, all the calibration measurements
are recorded for these detectors. “Start recording” is then displayed. The
calibration of the detectors with the help of the standard gas can begin.
For a detector in which the cell has been changed, it is important to adjust
the detector locally to obtain a 4-20mA output corresponding to the
detector range.
For detectors connected to the analog input module, perform the
adjustments directly on the module (see page 31).
Attention: During calibration, the standard gas must be injected for at
least thirty seconds.
■ No: Exits the recording procedure.
3. Stop recording
■ Yes: Detector calibration having finished, this validates the end of
calibration measurement recording for the detectors previously selected.
From this moment onward, no calibration measurement is recorded. “Stop
recording” is then displayed.
■ No: Exits the end of the recording procedure.
4. Validation
This allows the adjustment and validation of zero and detector sensitivity once
calibration is completed.

1. Select the detector to be calibrated with the help of the Previous detector
and Next detector keys and press Validate.
