thread port on the top cover. Check that the pump
adapter is mounted correctly. Avoid bending the
pump adapter. The gas detector automatically
switches to pump mode as soon as the pump
adapter is mounted.

2. When the leak test is displayed, the suction inlet on
the probe or hose closes within 60 s and remains
closed until the leak test is complete.
3. Release the inlet opening.
● Leak test successful: Measurement starts.
● Leak test failed: Inspect the accessories and the
pump adapter and then repeat the leak test.
4. Observe the flushing times. For further information,

4.7.3 Special state

The operation signal is deactivated during a special
state. Special states are displayed by the following
visual signals:
– Yellow LED flashing – 'warm-up 1' special state
– Yellow LED continuously illuminated – general
special state
No alarms are issued during a special state.
Exception: The calibration adapter is mounted in
measuring mode. In this case, alarms continued to be
issued as long as the measurement gas can reach the
sensors.
WARNING
Incorrect measurement!
A mounted calibration adapter blocks free gas diffusion
to the sensors. Correct measured values and alarms
can no longer be guaranteed.
► It is imperative to actively bump the sensors (e.g.
test gas cylinder with pressure reducer, flow
0.5 L/min).

4.7.4 Blocking alarm

The blocking alarm protects the CatEx sensor.
If the measuring range is exceeded significantly at the
CatEx channel (very high concentration of flammable
materials), a blocking alarm is triggered. This CatEx
blocking alarm can be acknowledge by switching the
gas detector off and then on again in fresh air.
For more details, refer to the technical manual.
