Operation
CAUTION
The volume of the horn is reduced!
If water gets into the opening on the horn (e.g. by immersing the gas detector in
water or due to heavy rain), the volume of the horn can be significantly reduced.
► With the display facing downward, shake the gas detector to remove the water.
Only using Bluetooth

or API applications is insufficient for raising the alarm in
safety-critical applications. Raising the alarm on the gas detector is decisive.
Contact Dräger for a description of the API interface.
Dräger recommends limiting the usage time at temperatures below -20 °C, as
the rechargeable battery life and the display may be restricted.
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 protection 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
2.
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 a menu is selected.
The STEL measurement is interrupted when the pump is connected and restarted
when the pump is removed.
The TWA measurement is paused when the pump is connected and continues
when the pump is removed.
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 Measuring mode
In normal measuring mode, the measured values are displayed for each measured
gas. The life signal sounds at regular intervals (configurable), and the green LED
flashes (e.g. visual life 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 applicable)
alternating with the measured values.
