An abrupt signal change (due to
feeding a gas mixture to sensor
atmosphere) or increased noise
on sensor optical elements.
Do not perform span calibration or
zeroing. If this status longer than for 20
minutes at stable conditions, replace
sensor.

Possibility of condensed moisture on
optical elements. Dry sensor. After
drying, if this status lasts longer than for
20 minutes at stable conditions, replace
sensor.
