Observe atmosphere
Do not use the device to test for combustible or toxic gases in the following atmos-
pheres as this may result in erroneous readings:
- Oxygen-deficient or oxygen-rich atmospheres
- Reducing atmospheres
- Furnace stacks
- Inert environments
- Atmospheres containing combustible airborne mists/dusts.
Use the device only to detect gases/vapours for which a sensor is installed.
The device is suitable and certified for the measurement of the oxygen concentra-
tion in gas mixtures for inertisation according to EN 50104 but without alarm func-
tion.
Make sure adequate oxygen is present for accurate combustible readings with the
catalytic sensor (>10% O
2
).
Not to be used for gases having a flashpoint in excess of 38 °C
Do not use the device to test for combustible gases in atmospheres containing va-
pours from liquids with a high flash point [above 38 °C], as this may result in erro-
neously low readings.
Physical shock
Recheck calibration if device is subjected to physical shock.
Sensor maintenance
Do not block sensor openings as this may cause inaccurate readings. Do not press
on the face of the sensors, as this may damage them and cause erroneous read-
ings. Do not use compressed air to clean the sensor holes, as the pressure may
damage the sensors.
Observe Proper Time for Display Stabilising
Allow sufficient time for device to display accurate reading. Response times vary
based on the type of sensor being utilized.
