NOTIFICATION
DESCRIPTION
Check the measurement cable for short-circuits
Replace the measurement cable Restart emission
Overpressure
Pressure measured exceeds the critical
value
Check for leaks
Wait until pressure reaches the minimum value
Restart emission
HV Failure
No high voltage at the gauge anode or
voltage value differs for over ± V from
nominal value
Check the connections of the controller
Replace the B-A gauge cable
Restart emission
Ubias Failure
Polarity voltage ( ilament voltage) dif-
fers for more than ± %
SCheck the measurement cable for short-circuits
Check the connections of the controller
Replace the measurement cable
Restart emission
Ref. Failure
Polarity voltage (re lector voltage) dif-
fers for more than ± %
Check the measurement cable for short-circuits
Check the connections of the controller
Replace the measurement cable
Restart emission
Degas Failure
Degassing procedure failed
Check the measurement cable for short-circuits
Replace the measurement cable
Restart the device
Low Pressure
Pressure in the gauge area is out of the
measuring range.
Check the gauge and its type whether it is appro-
priate for the application/process.
