Operation
4.4
Before entering the workplace
Switch on the instrument. The current measured values are shown in the display.
1. Switch on the instrument. The current measured values are shown
in the display.
2. Observe any warning or fault messages.
3. Check that the gas inlet opening on the instrument is not covered
or dirty.
4.5
During operation
During operation, the measured values for every measured gas
are displayed.
In the event of an alarm, the corresponding displays, including the
visual, audible and vibration alarms, are activated, see chapter 4.6
If a measuring range is exceeded or not reached, the following
displays are shown instead of the measured value display:
WARNING
Before any measurements relevant to safety are made, check
the adjustment with a bump test, adjust if necessary and
check all alarm elements. If national regulations apply, a bump
test must be performed according to the national regulations.
Faulty adjustment may result in incorrect measuring results,
with possible serious consequences.
CAUTION
The CatEx sensor is intended for measurements of flammable
gases and vapours mixed with air (i.e. O
2
content ≈ 21 vol.%).
Incorrect measured values may be displayed in the case of
oxygen deficient or oxygen enriched environments.
NOTICE
If the gas detector is used for offshore applications, a distance
of 5 m to a compass must be complied with.
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.

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
2
) 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
2
), the
explosion protection cannot be guaranteed; remove
instrument from the explosion-hazard area.
High off-scale readings may indicate an explosive
concentration.
