Specific settings
Pirani gauge
(AP 2004 - APN 2004)
Combined PIRANI/
Cold cathode gauge
(ACC 2009)
Switching function
(UR control).
No further settings for this gauge.
Description
This setting allows the set point contacts for this channel to be held
open or closed when the gauge indicates “UR” (Under Range =
pressure below the gauge’s measuring capabilities).
There are several possible causes of this “UR” indication:
- the pressure really is low
- the cold cathode gauge is not primed
- the gauge is faulty.
ON setting
Choose ON if you consider it abnormal for the gauge to have gone
UR. Previously activated set points will then be desactivated (detection
of UR status).
OFF setting
Choose OFF if you consider it normal for the gauge to have gone UR.
The set point contacts will then remain unchanged.
Access to this setting
