Leak Auto Start
= activation of the automatic start for leak rate measurement
P Damping
= selection of the damping value for the pressure measurement
Backlight
= adjust backlight
Key beep
= switch key tone on/off
Auto Switch Off
= selection of the time before the device goes into standby mode
Printer
= selection of printer protocol and printout of customer and tester
Touch pad
= calibration of the touchpad

17.1 Set clock
Setting the date, time and automatic acceptance of daylight-
saving time.
17.2 Activate automatic start for leak rate measurement
The automatic start enables the leak rate measurement in
pipelines with low to medium volume, which have a leak. Af-
ter closing the gas supply, the pressure in pipelines with low
volume would drop significantly and starting the leak rate
measurement manually would possible take too long and the
pressure in the pipeline would then be too low for a meas-
urement.
The measuring device recognizes a drop in pressure and
automatically starts the leak rate measurement.
However in rare cases, the pressure fluctuation in the gas pipeline is so high that the au-
tomatic operation causes an incorrect start of the leak rate measurement. In this case, the
automatic start must be disabled.
