Abstract
A fluid analyzer for analyzing fluid samples comprising one or more analytes and a method of calibrating such. The fluid analyzer includes a control system to control at least one automated valve to pass at least three calibration reagents through a fluid channel to a secondary ion selective electrode, a primary ion selective electrode, and a reference electrode, and determine calibration information using calibration logic from signals generated by a meter, control the at least one automated valve to selectively pass different subsets of the at least three calibration reagents through the fluid channel to the secondary ion selective electrode, the primary ion selective electrode, and the reference electrode, and determine re-calibration information using the signals generated by the meter and at least one of the calibration information and re-calibration logic.
