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 single-gas calibration or select
cancel 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 confirmation.
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.
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.
For the replacement of the battery, see the technical
manual.

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 (factory
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 deep-discharged, it may be necessary to
leave the device in the charging cradle for up to 16 h to
charge it.
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 an external power supply voltage drop > 1 s in the
charging cradle while the gas detector is in operation, the gas
detector switches off.
► Ensure uninterrupted power supply (does not apply if the
optional setting, that the gas detector does not
automatically turn off in the charging cradle, is selected). If
this cannot be ensured, regularly check that the gas
detector is turned on (e.g. based on the optical and
acoustic operating signals).
