Ps1 Mode
The Ps1 output can be in one of three modes: Measure, Leak or Control. The unit always powers-up in
Measure mode. The user must change to Control mode to move to a specific target. The user changes to
Leak mode (from Control mode) when performing a Leak check. After the Leak check is completed, the
unit automatically goes back into Control mode. So, during the entire operation of the tester, the user
should only stay between Control and Leak modes. The user should typically never have to go into
Measure mode.
How to change modes is described in Section 3.6.
