CHOOSE THE SENSOR TO BE RECALIBRATED AND PROCEED AS DESCRIBED (CO SENSOR
EXAMPLE):
Connect the known concentration gas cylinder to the instrument as shown in the following scheme:
WARNING!
Adequate ventilation must be provided when working with toxic gases, particularly the flow
meter and instrument outputs must be evacuated by a ventilation system.

4. In the following a detailed recalibration example will be described for O2 and CO sensors.
3. The 'On site calibration' menu shows the list of the installed sensors for which the recalibration is
available. In the recalibration screen all information related to the last performed calibration is shown,
as well as the relevant values.
