Operation
1.
Switch on the instrument. The current measured values are shown in the
display.
2.
Observe any warning
The instrument can be operated normally. If the warning message does not
disappear automatically during operation, the instrument must be serviced
after the end of use.
The instrument is not ready to measure and requires maintenance.
3.
Check that the gas inlet opening on the instrument is not covered or dirty.

WARNING
Explosion hazard! To reduce the risk of ignition of a flammable or explosive
atmosphere, strictly adhere to the following warning statements:
Fractions of catalytic poisons in the measuring gas (e.g. volatile silicium,
sulphur, heavy metal compounds or halogenated hydrocarbon) can damage
the Cat Ex sensor. If the CatEx sensor can no longer be calibrated to the
target concentration, the sensor must be replaced.
In case of measurements in oxygen-deficient atmosphere (<12 vol.% O
the CatEx sensor may show incorrect displays; in this case, a reliable
measurement with a CatEx sensor is not possible.
In an oxygen enriched atmosphere (>21 vol.% O
cannot be guaranteed; remove instrument from the explosion-hazard area.
High off-scale readings may indicate an explosive concentration.

During operation
During operation, the measured values for every measured gas are
displayed.
In the event of an alarm, the corresponding displays, the visual, audible and
vibration alarms are activated – see Chapter "Identifying alarms" on
Page 37.
If a measuring range is exceeded or not reached, the following displays are
shown instead of the measured value display:

« (below measuring range) or
