Heating (Activation/Conditioning) without stop
Some applications require special getter pumps (HV) that work when the getter material is hot.
NEG POWER can be used to keep these pumps hot giving them the necessary power
continuously. To do this, t_hold =
is used (to set t_hold =
reduce t_hold down to 100 and
press down again). When t_hold =
the power supply is only stopped by pressing the stop
button.
