Basic operation of the leak detector
Preliminary about
C 60 &
C 61
The operation of the leak detector is explained in
C 60
and
C 61.
■ If the factory configuration does not need to be changed,
please read this chapter.
■ If operator needs more information or needs to change the
C 61
factory configuration, he must read this chapter and
where the following points are explained:
➪ hard vacuum test mode (information)
➪ selecting a test mode
(adjustment)
➪ sniffer probe
(information)
➪ sniffer probe reject point (adjustment)
Factory configuration
C 10
Two test methods are possible with the leak detector:
➪ hard vacuum test
➪ sniffing test.
Hard vacuum test
Starting a test cycle
Make sure that the parts can withstand the
difference in internal / external pressure to which
they are subjected.
Connect the part or the
installation to be tested to
the inlet port of the leak
detector.

The leak detector reaches the Gross
Leak test mode, the Normal test mode
or the High Sensitivity test mode
according to test mode selection.
The digital display shows the leak value.

The helium signal analog scale displays the leak
value in 2 colors following the measured leak value:
➪ reject point is visualized by a blinking led.
➪ if the leak value exceeds the reject point, the leds
will turned red (the blinking led will turn orange).
➪ if the leak value remains under the reject point,
the leds will remain green.

At the end of a test cycle, 2 possibilities are available:
➪ venting (inlet of the leak detector is back to atmospheric
pressure)
➪ not venting (keeping under vacuum) the part or tested
installation remains under vacuum.
