Fig. 7-23 Residual Oxygen Meter
An error has occurred at the residu-
al oxygen meter.
Possible causes:
• Flow is impaired.
• The filter at the residual oxygen
meter is contaminated.
• Residual oxygen meter is defect
Please refer to the included docu-
mentation regarding the
residual oxygen meter for additional
details.
Fig. 7-24 Nitrogen Connections and Residu-
al Oxygen Meter
The residual oxygen value in the
heating chamber has exceeded the
value set in the N2 operation mask
limit tolerance value.
Possible causes:
• Inadequate maintenance.
• The nitrogen settings are incor-
rect. Check the fixed settings in
the calibration report!
• One of the process chamber
seals is leaky.
• The residual oxygen meter is
hooked up incorrectly (standard:
