Charging instrument with NiMH power pack T4
(HBT 0000 type)/ T4 HC (HBT 0100 type
Danger of explosion!
Do not charge underground or in explosion hazard areas!
The chargers are not designed in accordance with the regulations for
firedamp and explosion protection.
Danger of explosion!
Charge the NiMH power pack T4 (HBT 0000 type) or T4 HC (HBT 0100 type)
using the corresponding Dräger charger. Ambient temperature during the
charging process: 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.

To maintain the lifetime of the batteries, charging is temperature controlled and
only performed in a temperature range of 5 to 35 °C. When this temperature
range is left, the charging 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 (maximum 2 months) without being connected to a power source, as this
drains the internal buffer battery.
Carrying out the bump test
Refer to the Technical Manual for a description of the automatic function test
using the bump test station.
 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).
Never inhale the test gas. Health hazard!
Observe the hazard warnings of the relevant safety data sheets.

 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 setpoints 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 calibrated by the service personnel.
Calibration
Calibration may not be possible due to instrument and channel errors.
Carrying out the fresh air calibration
Calibrate the instrument to fresh air, free of measured gases or other interfering
gases. During the fresh air calibration, the zero point of all the sensors
