10.0 Error message list

Error display

Malf unct ion

Treat ment

ErrA

Atmosphere adjustment is tried at
inadequate pressure (perhaps in
vacuum)

Make sure the gauge is at
atmosphere before adjustment

ErrU

Zero adjustment is tried at
insufficient vacuum

Perform the zero adjustment in
sufficient vacuum

Erro

Crystal sensor oscillation error

Needs crystal sensor replacement.
Contact service agent.

AdEr

A/D converter error

Needs electronics repair. Contact
service agent

CALE

A/D converter calibration error

Needs electronics repair. Contact
service agent

EE Error

(scroll display)`

EEPROM error

Needs electronics repair. Contact
service agent

Troubleshooting

Symptom

Possible Cause

Treatment

No display appears

Power failure

Check connector. Check power (24
VDC) supply

Pressure reading is

unstable

Contamination in the
sensor

Sensor cleaning

Pressure reading and HV
LED are blinking

Cold cathode sensor
is not ignited
(possibly the
pressure is low
when power is
turned on)

In low pressures cold cathode
sensor tend to take a little long time
to ignite. Wait until the pressure
reading appears.

Pressure display does not
decrease under 7.5E-3 Torr

Crystal zero is
shifted

Perform manual zero adjustment
when the pressure is below 4E-5
Torr
