Risk to health! Never inhale the test gas.
Observe the hazard instructions of the appropriate
Safety Sheets.
CAUTION
!
A functional test must be carried out on every device
before use.
Safe pump operation is only ensured when the
functional test is performed after each mounting of the
holder.
NOTICE
i i
Sensor-specific features are described in the relevant
sensor data sheets.
The functional test can be carried out in 3 ways.
3.4.1 Functional test of the X-am 5000/5600
Perform a functional test in accordance with the

instructions for use for the gas detection instrument before
using with the X-zone 5500.
3.4.2 Functional test of the X-am 5600 in combination
with the X-zone 5500
In diffusion mode
1. Switch on the X-zone 5500 (see" Switching on the
instrument" on page 44).
2. Attach adaptor (1) (order no. 83 23 314) to the holder
(diffusion).
3. Connect the test gas cylinder hose to the adaptor (2).
4. Open the test gas cylinder valve to let test gas flow over the
sensors.
5. Wait until the device displays the test gas concentration
with sufficient tolerance:
Ex: ±20% of the test gas concentration
1
O : ±0.8 vol.%
2
TOX: ±20% of the test gas concentration
1 Upon application of the Dräger mixed gas (order no. 68 11 130)
the displays should be within this range. Different concentrations
can be set using the Dräger CC-Vision PC software provided.
