Each sample ADC is actually an average of eight readings. The ADC
difference between the minimum and maximum readings must be less
than the predefined limits a noise flag will occur. This does not apply to CO
The average of the eight ADC readings corresponding to the measurement
of the Electrolyte Reference Solution.
For CO , the reference ADC represents the rate of pH change initiated by
2
the reference reagent.
Each reference ADC is actually an average of eight readings. The ADC
difference between the minimum and maximum readings must be less
than the predefined limits, otherwise a noise flag will occur.
The difference between the average of the Sample-Reference values
reported for each calibrator level. The value is compared to an expected
value and if the calculated span is less than the expected span, the
calibration is flagged.
The concentration value assigned to the calibrator level.
The units assigned to the set point value.
The field indicating which replicate of a calibrator level is used for a
particular chemistry.
The fields listed below categorize information about a failed calibration.
Multiple errors are shown here for any chemistry failure. The errors should
correlate with any of the asterisked (*) fields listed within the calibration
report. This section of the report appears only when a calibration fails.
• Reagent – Identifies the failed chemistry.
• Level – Identifies the calibrator level which failed.
• Condition – In the event that an error occurs, an asterisk (*) appears
next to the value which is out of specification. The corresponding error
flag will print in this field. Only those errors that FAIL the calibration will
print.
