Carrying Out A Cross Calibration; Carrying Out A Signal Test; Charging The Battery - Dräger HFG 000 Series Technical Manual

If there was an error during the multi-gas calibration:
– Repeat the multi-gas calibration or carry out a 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.
– If necessary, replace the sensor.For further information, see the following
chapter: "Exchanging, adding or removing a sensor", page 48

Carrying out a cross calibration

If the respective gas combination and the sensor are released, an automatic cross
calibration and test can be set with the Dräger CC-Vision PC software.
With the gas-switch wizard in the Dräger CC-Vision PC software, a gas can be
selected for the bump test, the calibration and the measurement gas. This
automatically carries out conversions, omitting the need for these to be done
manually.
The settings are also used by the Dräger X-dock maintenance station.

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.
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. The green LED on the power
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.
