CHAPTER 12
Troubleshooting Calibration and Result Errors
Calibration Errors
Introduction
The following pages contain descriptions of calibration reports for linear, non-linear, electrolyte
module, and cup module chemistries and explanations of what each field on the report is used for
when calibrating each chemistry type.
Calibration Error Checking
Calibration and Result Error checking is used to flag system and reagent issues. Error checking is
performed on the final result and on interim steps of the reaction. The error flags may be directed
to a calculated calibration factor or to any of the interim data used to generate a final calibration
result. The flags may be indicative of a variety of different hardware, reagent, or sample (calibrator)
issues and can be used to troubleshoot different system issues. Any calibrator or sample outside of
any one or more calibration limits will be flagged.
Calibration Error Flags
Table 12.1 below is a general list of the calibration errors for linear, multipoint, and MC calibrations.
These errors are listed in the "Failed Calibration Report" area of the calibration report. Descriptions
of each of the calibration error flags are listed, in more detail, by calibration type in the following
sections.
