WARNING
Health hazard from test gas
Breathing in of test gas can be harmful to health or lead to death.
► Do not inhale the test gas.
► Observe risks connected with the test gas, hazards notes and safety advice (see
for example safety data sheets, instructions on the testing media).
1. Connect the test gas cylinder to the calibration adapter (order no. 8318752).
2. Connect the hose to the second connector on the calibration adapter to direct
the test gas to an exhaust or outside.
3. Insert the switched-on gas detector into the calibration adapter and press it
down until it locks into place.
4. Press for approx. 4 s in measuring mode.
5. Enter and confirm the password.
6. Select and confirm mixed gas calibration .
All measuring channels are shown and flash.
The channels must be activated for the mixed gas calibration using the
Dräger CC-Vision PC software.
7. Press to start the mixed gas calibration.
8. Open the test gas cylinder valve, the volume flow must be 0.5 L/min.
9. Wait until the measured values displayed are stable and then confirm with .
 The display containing the current gas concentration changes with the
display OK.
10.Press .
● Select to confirm the measured values and switch to the measuring
mode.
● Select to discard the measured value and return to the mixed gas
calibration.
● Select to return to the measured value.
11.After successful mixed gas calibration, close the test gas cylinder valve and
remove the gas detector from the calibration adapter.
Further steps
If an error occurred during mixed gas calibration, the fault message X is displayed
and -- is displayed for the affected measuring channel instead of the measured
value. In this case, repeat the mixed gas calibration or replace the sensor, if
necessary.
6.8 Charging the battery
To protect the battery, charge only in the temperature range of 5 to 35 °C. Outside
this temperature range, the charging process is automatically interrupted and
automatically continued after the temperature range has been reached again. The
charging time is typically 4 h. A new NiMH power pack reaches its full capacity after
3 complete charge/discharge cycles. Never store the gas detector for extended
periods without being connected to a power source (maximum of 6 months)
because the internal buffer battery will drain.
