Probable causes
Sector motor rotation detector
signal is faulty.
A/D conversion signal is faulty.
Zero calibration is not within the
allowable range.
A amount of zero calibration
(indication value) is over 50% of
full scale.
Span calibration is not within the
allowable range.
A amount of span calibration
(difference between indication
value and calibrated concentration
value) is over 50% of full scale.
Measured values fluctuate to much
during zero and span calibration.
Calibration is abnormal during auto
calibration.
Output cable connection is improper.
