7.2.8
Sensor Switch-off Value (t-off)
This parameter will only appear when the sensor switch-off type has been set to CH 1, CH
2 or CH 3 (
Chapter 7.2.7 Sensor Switch-off type (S-oFF), page 32).
Through the parameter t-off you can define a switch-off value. If the pressure in the
respective measurement channel exceeds the switch-off value, the PENNINGVAC sensors
PTR81N, PTR225, PTR225N, PTR225S, PTR225SN, PTR237 and PTR237N are switched
off.

General Parameters (PArA GEn)
With the aid of these parameters you can generally configure the instrument. The
parameters apply to all measurement channels.
Keep the pushbutton PARA depressed for approximately 2 seconds.
The instrument is now in the parameter mode.
Use the arrow pushbuttons so as to access the parameter group GEn.
Press the pushbutton PARA to select the desired parameter.
The name and the value of the parameter are displayed.
Use the arrow pushbuttons so as to change the parameter setting.
Repeat the steps so as to change further parameters of the parameter group.
