6.8 Perform regeneration
On a daily basis, before switching off the device and mainly after a series of
successive measurements, the gases frozen in the cryogenic pump must be
evaporated and removed from the system.
► Perform daily regeneration of the cryogenic pump.
After the regeneration is started, the heating phase is started after a pre-warning
period. The temperature in the cryogenic pump increases and the frozen gases are
evaporated and pumped out, depending on their dew point.
