Correction
Turn on power supply.
Replace ionization cham-
ber or measuring cham-
ber cpl (→ 44, 50).
Wait, until the gas dis-
charge has ignited
(≈5 minutes at a pressure
of 10
-9
mbar).
Perform a HV adjustment
via button (→ 41).
Replace the measuring
chamber cpl. (→ 50).
Switch the gauge off and
on again after 5 s.
Replace the gauge.
Replace the measuring
chamber cpl. (→ 50).
Possible cause
No supply voltage.
Gauge contaminated.
Gas discharge has not
ignited.
Pirani zero point shift.
Pirani defective.
EEPROM error.
Measuring chamber
severely contaminated.
