During Operation - Dräger X-am 5000 Notice D'utilisation

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
protection 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".
– If a measuring range is exceeded or not reached, the following displays are
shown instead of the measured value display:
» « (measuring range exceeded) or
)
» « (below measuring range) or

– After the measuring range of the TOX measuring channels has been
exceeded temporarily (up to one hour), checking the measuring channels is
not necessary.
Special states in which there is no measuring operation (quick menu,
calibration menu, warm-up of sensors, password input) are indicated by a
visual signal (slow flashing of the alarm LED

If the DrägerSensor CatEx 125 PR is used in the gas detector, a zero point and
sensitivity calibration must be carried out after experiencing an impact load that
results in a non-zero display when exposed to fresh air. This warning does not
apply if the DrägerSensor CatEx 125 PR Gas is used.
