4.7.1 Monitoring measuring mode
In normal measuring mode, the measured values are
displayed for every measurement gas (see Graphic E
on the fold-out page). The operation signal sounds at
regular interval (configurable), and the green LED
pulses (e.g. visual operation signal or D-light feature).
If a measuring range is exceeded or not reached, the
respective symbol is displayed instead of the measured
value. For further information, see the following
chapter: "Symbol explanations", page 33
If, in measuring mode, a event (e.g. an alarm) occurs,
the respective symbol is displayed in the status bar
(after the event is acknowledged, if necessary).
4.7.1.1 Displaying the measuring channel
To display an individual measuring channel:
1. Select in measuring mode.
2. Use ▲ or ▼ to view the individual measuring
channels.
3. Select to navigate to the measuring channel
overview.
4.7.1.2 Opening the event report
The event report must be switched off in order to
comply with the requirements for the technical
suitability test.
If the gas detector is switched off and then on again,
the event report is deleted.
The following events are counted and displayed: A1/A2,
STEL, shocks, incorrect password entries.
To open the event report:
1. Select > Status > Device information in
measuring mode.
2. Use ▲ or ▼ to scroll through the individual pages
until the event report.
The symbol indicates a failed sign-on only after 5
attempts.
4.7.1.3 Activating the pump
To activate the pump in (normal) measuring mode:
1. Place, align and tighten the pump adapter on the
thread port on the top cover. Check that the pump
adapter is mounted correctly. Avoid bending the

pump adapter. The gas detector automatically
switches to pump mode as soon as the pump
adapter is mounted.
 The leak test starts automatically.
2. When the leak test is displayed, the suction inlet on
the probe or hose closes within 60 s and remains
closed until the leak test is complete.
3. Release the inlet opening.
● Leak test successful: Measurement starts.
● Leak test failed: Inspect the accessories and the
pump adapter and then repeat the leak test.
4. Observe the flushing times. For further information,
see the following chapter: "Special features when
measuring with the pump", page 39
4.7.2 Alarms
In the event of an alarm, corresponding displays, the
optical alarm, vibration alarm as well as, if necessary,
the acoustic alarm are activated (configurable). For
further information, see the following chapter: "Alarm
settings (factory setting)", page 48
To acknowledge an alarm:
1. Select .
4.7.3 Special state
The operation signal is deactivated during a special
state. Special states are displayed by the following
visual signals:
– Yellow LED flashing – 'warm-up 1' special state
– Yellow LED continuously illuminated – general
special state
No alarms are issued during a special state.
Exception: The calibration adapter is mounted in
measuring mode. In this case, alarms continued to be
issued as long as the measurement gas can reach the
sensors.
The special state is exited by resolving the potential
error, in the event of an intact gas detector, by switching
to normal measuring mode, or automatically after
approx. 1 minute.
