CALIBRATION EXAMPLE FOR THE OXYGEN CELL (O
2
).
→
Apply gas to the instrument and adjust the output pressure of the gas from the cylinder so that the flow meter
indicates a minimum flow of 0.5 l/m: this guarantees that the instrument is taking the exact amount of gas
required by the internal pump.
The calibration will be possible only when the status is set to ‘----' (cells which never had an on-site calibration)
or 'inactive'.

The instrument measures the concentration of gas applied; wait at least 3 minutes to allow the reading to
stabilize. The reading is shown in line 'Gas measured'.
