4.5.4 "Leak tightness check” function
Press the "Mute" button and keep it pressed until the "Alarm" signal
lamp flashes quickly, then release. A value for the leak tightness is
shown on the display (103). The same value is indicated by the num-
ber of times the “Alarm” signal lamp flashes.
After 10 seconds this display goes off and the current underpressure
in the system is shown again.
For the "Test leak tightness" function, the leak detector must have
performed at least 1 automatic feed interval in normal operation (i.e.
without being filled/evacuated by an assembly pump) in order to ob-
tain a valid result.
It is recommended to make this test before performing any recurring
functional test of a leak detector. This makes it possible to directly as-
sess whether to look for leaks.
Number of flashing signals Assessment of the leak tightness
0
Very leak tight
1 to 3
Leak tight
4 to 6
Sufficiently leak tight
7 to 8
Maintenance recommended
9 to 10
Maintenance urgently recommended
The smaller the above value, the tighter the system is. The meaning-
fulness of this value also depends on temperature fluctuations and
should therefore be considered an indicative value.
