Test gas concentration of other gasses:
Refer to the Dräger CC-Vision PC software
1) Only X-am 8000
2) Depending on the measuring range and the measuring accuracy.
Dräger recommends selecting a test gas concentration in
the middle of the respective measuring range or close to the
expected measured value.
To carry out a single-gas calibration:
1. Mount the calibration adapter to the gas detector. Make
sure that both guide pins are in the correct grooves. Avoid
putting the pump adapter at the wrong angle.
2. Connect the test gas cylinder to the calibration adapter.
3. Connect a second hose (max. length: 2 m) to the second
connector on the calibration adapter to direct the test gas
to an exhaust or outside.
4. Switch on the gas detector.
5. Select
> Login.
6. Enter and confirm the password.
7. Select Maintenance > Single gas cal..
A dialog for selecting the measuring channel to be
calibrated appears.
8. Select the measuring channel.
A dialog for selecting the calibration appears.
9. Select either zero-point calibration or span calibration.
● For a span calibration: Enter and confirm the
calibration concentration.
10. Open the valves on the test gas cylinder.
11. Select
to start the single-gas calibration or select
cancel the calibration.
The measuring channel appears, and the measured
value flashes.
As soon as the stability check detects a stable
measured value, a calibration is carried out
automatically.
12. If necessary, press
this case, a calibration happens immediately.
The new measured value is displayed for control
purposes.
The result is displayed as follows:
single-gas calibration successful.
single-gas calibration failed.
13. The single-gas calibration is complete when measuring
channel successfully passed or failed the single-gas
calibration.
● Select
and then confirm the dialog to discard the
result.
● Select
to confirm the result.
14. Close the valves on the test gas cylinder.
15. Remove the calibration adapter.
16. After completing the measurement, make sure that the
seal on the calibration adapter is clean and that there are
no chips of metal on the seal.

Plug the protective cap onto the calibration adapter to
protect the seal from damage and being deformed.
If there was an error during the single-gas calibration:
– Repeat the single-gas calibration.
– Inspect the sealing contours and surfaces on the
calibration adapter as well as the front cradle of the
housing to make sure they are free of damage. Inspect the
thread port for the calibration adapter.
– If necessary, replace the sensor.
For mixed gas and cross calibration, see the technical
manual.

Charging the battery
WARNING
Risk of explosion!
To reduce the risk of ignition of a flammable or explosive
atmosphere, observe the following:
► Do not open the gas detector in explosion-hazard areas.
► Only use the LBT 02** (lithium-ion) battery type.
► Do not charge or exchange the battery in explosion-
hazard areas.
► Only use the battery charger specified by Dräger. The use
of a different charger nullifies the explosion protection
certification of the gas detector.
Refer to the Technical Manual when replacing the battery.
The battery is a part of the lower part of the casing. The
battery can be charged with or without the gas detector.
1. Place the gas detector or only the lower part of the casing
with the battery in the charging cradle.
The gas detector switches off automatically (default
to
setting). The green LED on the power pack flashes.
The typical charging time after a work shift of 8 – 10 h is
approx. 4 h.
The typical charging time for an empty battery is approx. 10 h.
If the battery is exhaustively discharged, it may be
necessary to leave the device charging in the charging cradle
for up to 16 h.
If the specified temperature range (5 to 35 °C) is not reached
or is exceeded, charging stops automatically. This extends the
charging time. After a return to the temperature range,
charging continues automatically.
WARNING
No measurement!
If there is a voltage dip in the power supply lasting longer than
1 s during operation of the gas detector in the charging cradle,
the gas detector will switch off.
► Ensure there is an uninterruptible power supply (this does
not apply if the optional setting that the gas detector does
not automatically switch off in the charging cradle is
selected). If this cannot be guaranteed, check regularly
that the gas detector is switched on (e.g. using the visual
and acoustic life signal).
