Heating (Activation/Conditioning) Without Stop; Custom: A Generic Pump For Customer Settings - SAES NEG POWER User Manual

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.

Custom: a Generic Pump for Customer Settings

NEG POWER software is preset to know the activation/conditioning parameter settings of the most
popular SAES getter pumps, like the GP SORB AC, the CapaciTorr, CapaciTorr HV and the
NEXTorr families (see the Summary Table of the NEG pumps controlled by the NEG POWER).
In the software there is also a Generic Pump named Custom.
If the used pump model isn't included in the list, Custom pump can be selected and settings of
suitable voltage, current, power and temperature must be set for the specific pump model.
The default settings for Custom pump are the following. These values can and shall be changed.
