en Operation
To end the confined space entry measurement:
1. Select during the confined space entry
measurement and confirm the dialog.
 A dialog for performing another confined space
entry measurement is displayed.
2. Select to end the wizard.
3. Remove the pump adapter.
4. Return to normal measuring mode.
4.14 Carrying out leak searches with
the wizard
During a leak search, the duration of the measurement
(in mm:ss) is displayed for a maximum of one hour in
place of the time and the measured values can be
displayed in the form of a bar chart (configurable with
the CC-Vision PC software). Afterwards, the time is
displayed again. The measurement duration is
restarted after each flow alarm.
During a leak search, the Clear app. peak feature
should be stored in the quick menu using the Dräger
CC-Vision PC software. This feature can be used to
delete the application values in the bar chart.
Because of the physical flushing times, Dräger
recommends carrying out measurements with the leak
search wizard without a hose/probe or with only a short
hose (max. 2 m).
Requirements:
– The gas detector is equipped with a pump and is
switched on.
– All installed sensors are warmed up.
– The gas detector is ready to take measurements.
To carry out a leak search:
1. Sign in with the required user level.
2. Select > Leak search in measuring mode.
3. Confirm the successful leak test to start the
measurement.
The device emits tones in the "Individual measuring
channel" display which increase in frequency as the gas
concentration increases. If the pre-alarm threshold is
reached, the gas alarm appears.
To end the leak search:
1. Select in leak search mode and confirm the
dialog.
2. Remove the pump adapter.
3. Return to normal measuring mode.
4.15 Carrying out a benzene/pre-tube
measurement with the wizard
Observe the instructions for use of the respective
tube!
The use of a pre-tube is only possible when using the
wizard.
During the benzene/pre-tube measurement, the visual
alarm, acoustic alarm, vibration alarm and alarm
evaluation are deactivated.
A benzene/pre-tube measurement (photoionization
detector) with a pre-tube (e.g. benzene pre-tube) can
only be done with the benzene/pre-tube wizard.
During the benzene/pre-tube measurement, the gas to
be measured and the PEAK values are visible on the
display. All other sensors are not evaluated.

4.15.1 Mounting the pre-tube bracket

Fast temperature and humidity changes influence
the measured signal. If temperature and humidity jumps
are anticipated, Dräger recommends using a damp pre-
tube for the measurement.
1. Mount the pump adapter to the gas detector. Make
sure that both guide pins are in the correct grooves.
