Charge instrument with NiMH power pack T4
(Type HBT 0000) / T4 HC (Type HBT 0100)
Explosion hazard! To reduce the risk of ignition of a flammable or explosive
atmosphere, strictly adhere to the following warning statements:
Do not charge underground or in explosion hazard areas!
The chargers are not designed in accordance with the regulations for fire
damp and explosion protection.
Charge NiMH power packs T4 (type HBT 0000) or T4 HC (type HBT 0100)
with the appropriate Dräger charger. Ambient temperature during charging:
0 to +40 °C.
Even if the instrument is not used, we recommend that you store the instrument
in the charger!
 Insert the switched off instrument into the charger.
– Display LED on the charger:

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 hours. A new NiMH power pack
reaches its full capacity after three complete charge / discharge cycles. Never
store the instrument for extended periods without being connected to a power
source (maximum of 2 months) because the internal buffer battery will drain.

WARNING
Carry out manual bump test
The automatic function test with the Bump Test Station is described in the
Technical Handbook.
 Prepare a test gas cylinder, the volume flow must be 0.5 l/min and the gas
concentration must be higher than the alarm threshold concentration that is
to be tested.
 Connect the test gas cylinder with the calibration cradle (order no. 83 18 752).
Health hazard! Never inhale the test gas.
Observe the hazard warnings of the relevant Safety Data Sheets.
CSA requirement: carry out a bump test before use. It should be carried out in
the measuring range 25-50 % of the full scale value, whereby the displayed
measured value may deviate from the actual measured value by 0-20 %.
Accuracy may be corrected via calibration.
 Switch on the instrument and insert it into the calibration cradle – press
downwards until it engages.
 Open the test gas cylinder valve to let test gas flow over the sensors.
 Wait until the instrument displays the test gas concentration with sufficient
tolerance –
Ex: ±20 % of the test gas concentration
1)
O : ±0.6 vol. %
2
TOX: ±20 % of the test gas concentration.
– If the alarm thresholds are exceeded, the instrument displays the gas
concentration in alternation with » A1 « or » A2 « depending on the test gas
concentration.
 Close the test gas cylinder valve and remove the instrument from the
calibration cradle.
If the displays are outside of the above-mentioned ranges:
 Have the instrument adjusted by the service personnel.
1) During application of the Dräger mixed gas (order no. 68 11 130) the displays should be within
this range.
