► To define the duration in which the test chamber is purged with purge gas, set the
time.
Short regen after Gross Leak
Short-term heating of the cryogenic pump after a gross leak test to remove helium
from the cryogenic pump. This function is activated by default.
After a gross leak test, helium atoms are located between the purge gas atoms on the
surface of the cryogenic pump. In order to avoid increased leakage rates during
subsequent measurements by means of this helium fraction, the cryogenic pump is
heated up briefly, but only when during the gross leak test a gross leak is detected, so
that the helium components can be evaporated and removed from the system.
