Operation
WARNING
Incorrect measured values!
A different reading may be shown if the gas detector experiences a considerable
impact or a significant vibration.
► When using a CatEx or IR sensor (depending on the gas detector type), a
calibration of zero-point and sensitivity must be carried out after an impact
load that results in a fresh air display not equal to zero.
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
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 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 a menu is selected.
The STEL measurement is interrupted when the pump is connected and
restarted when the pump is removed.
