7.3.2 Pollution function
This is a safety device for the detector. It prevents too much leaked tracer gas from pe
-
netrating the detector. We recommend setting the pollution set point to a maximum of 4
decades above the reject set point. If the leak rate rapidly increases above the pollution
set point, the cycle stops automatically and the leak detector returns to Stand-by mode.
7.3.3 Hard Vacuum reject point
The hard vacuum reject point defines the acceptance set point for parts that are "accept-
ed/rejected" in a hard vacuum test:
– Measured leak rate ≤ reject set point: part accepted
– Measured leak rate > reject set point: part rejected
The reject set point is memorized for each configurable tracer gas.
