Maintenance
2. Connect the hose to the second connector on the
calibration adapter to direct the test gas to an exhaust or
outside.
3. Insert the switched-on gas detector into the calibration
adapter and press it down until it locks into place.
4. Press
for approx. 4 s in measuring mode.
5. Enter and confirm the password.
6. Select and confirm the single-gas calibration .
The first measuring channel is displayed and the
measured gas flashes.
7. Use
to select the desired measuring channel.
8. Press
to start the single-gas calibration for the selected
OK
measuring channel.
The test gas concentration is displayed and flashes.
A 2-stage calibration routine takes place with the CO
channel: The zero calibration takes place first, followed by
the span calibration.
9. Press
to confirm the test gas concentration, or use
OK
to change the test gas concentration and confirm with
The measured value flashes.
10. Open the test gas cylinder valve, the volume flow must be
0.5 L/min.
11. Wait until the displayed measured value is stable then
confirm with
.
OK
The display containing the current gas concentration
changes with the display OK.
12. Press
.
OK
● Select
to confirm the measured value. The next
measuring channel is displayed for calibration, if
necessary. After the last measuring channel has been
calibrated, the gas detector changes to measuring
mode.
● Select
to discard the measured value and to return
to the measuring channel selection.
● Select
to return to the measured value.
13. After successful single-gas calibration, close the test gas
cylinder valve and remove the gas detector from the
calibration adapter.
Further steps
If an error occurred during single-gas calibration, the fault
message X is displayed and -- is displayed for the affected
measuring channel instead of the measured value. In this
case, repeat the single-gas calibration or replace the sensor, if
necessary.
For mixed gas and cross calibration, see the technical
manual.

Charging the battery
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 h. A new NiMH power
pack reaches its full capacity after 3 complete
charge/discharge cycles. Never store the gas detector for
30
extended periods without being connected to a power source
(maximum of 6 months) because the internal buffer battery
will drain.
The buffer battery can be replaced if necessary.
WARNING
Risk of explosion
To reduce the risk of ignition of a flammable or potentially
explosive atmosphere, observe the following:
► Do not charge or replace the battery in potentially
explosive atmospheres or 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.
● Insert the gas detector into the charger module.
2
If the gas detector is switched on, then it is automatically
switched off after being inserted.

Replacing the battery

OK
WARNING
Risk of explosion
To reduce the risk of ignition of a flammable or potentially
explosive atmosphere, observe the following:
► Do not open the gas detector in explosion-hazard areas.
► Only the battery types specified in the technical data must
be used.
► Do not charge or replace the battery in potentially
explosive atmospheres or in explosion-hazard areas.
► Check that the fastening screw of the battery pack is
secure before use.
NOTICE
Damage to the gas detector
The power pack for the X-am 2500/5000/5100/5600 gas
detectors (order no. 8318704) must not be used for the X-am
2800, as the seal cannot ensure the IP protection for the X-am
2800 and was not approved together with the X-am 2800.
► Only use the battery pack (order no. 3703887) with visible
part number 3703880 as power pack.
1. Switch off the gas detector.
2. Undo the screw on the power pack.
3. Remove and replace the NiMH power pack T4 (type HBT
0010).
4. Insert the power pack into the gas detector and tighten the
screw, the gas detector switches on automatically.
5.9
Cleaning
The gas detector does not require any special care.
If it is heavily soiled, wash off the gas detector with cold water,
using a sponge if necessary. Dry the gas detector with a cloth.
