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 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.
