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.
5.6 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.
The gas detector can be switched on again in the
charging cradle and is then supplied with electrical
current during operation.
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).
