WARNING
!
Always adjust the zero point first, before the sensitivity,
otherwise the adjustment will be incorrect!
Adjustment may not be possible due to instrument and channel

Performing a fresh air calibration

Calibrate the instrument to fresh air, free of measured gases or

Performing a standard sensitivity calibration

CAUTION
!
Never inhale the test gas. Danger to health!
Observe the hazard warnings of the relevant Safety Data
Sheets.
NOTICE
i i
To minimise adsorption effects, keep the length of the hose
as short as possible (maximum hose length: 1 m). Dräger
recommends using PTFE hoses.
During the sensitivity calibration, the sensitivity of the sensor is set to
the value of the test gas.
1. Fit the calibration adapter (68 06 291) to the sensor cap.
2. Connect the test gas source to the calibration adapter.
3. Vent the test gas into a fume cupboard or into the open air
«
(with a hose connected to the second connector of the calibration
adapter).
4. Switch on the instrument.
5. Press the key and keep it pressed for 5 seconds to call the
calibration menu.
