Operation
At temperatures below -25 °C, there may be limitations to what is shown on
the display. Dräger then recommends only using the alarm elements as a
display.
WARNING
High readings outside of the LEL display range or a blocking alarm may indicate
an explosive concentration.
If the concentrations of combustible gases are too high, this may be the result of
a lack of O .

The IP degrees of protection do not extend to instances in which the equipment
detects a gas during or after its exposure to these conditions. In the case of dust
deposits and contact with water by immersion or a jet of water, check the
calibration and functional integrity of the device.
The PEAK, STEL and TWA evaluations are interrupted if the menu is selected.
Selecting the Quick menus has no influence on the PEAK, STEL and TWA
evaluations.
The STEL values are reset when a bump test is started, irrespective of whether
the bump test is successful or is cancelled.
If the gas detector is used for offshore applications, it must be kept at least 5 m
away from compasses.

4.6.1 Monitoring measuring mode

In normal measuring mode, the measured values are displayed for each
measured gas. The operating signal sounds at regular intervals (configurable),
and the green LED flashes (e.g. visual operating signal or D-light feature).
If a measuring range is exceeded or not reached, the respective symbol is
displayed instead of the measured value.
If, in measuring mode, an event (e.g. an alarm) occurs, the respective symbol is
displayed in the status bar (after the event is acknowledged, if necessary)
alternating with the measured values.

4.6.2 Alarms

In the event of an alarm, corresponding displays, the visual alarm, vibration
alarm as well as the audible alarm are activated. For further information, see the
following chapter: "Alarm settings (factory setting)", page 63
