General information
Calibration is the process that relates the electrode signals during the calibration
sequence to the values of the calibrating solutions and air. Calibration enables
the electrode signals to be converted to the accurate values for an unknown
sample.
Calibration must be performed at regular intervals so that normal variations in
sensor output can be compensated for after inevitable minor changes in the
sensor's behavior.
Calibration of all sensors is performed using air, CAL 1 (also used for rinse), CAL
2 and CAL 3 (see chapter 9, Solutions for more information on the solutions).
The calibration solutions contain known concentrations of the substrates to be
measured. These concentrations are vital in determining the measurement
accuracy of the analyzer.
The concentration of each substance in the calibration solutions is programmed
into the integrated smart chip of the solution pack. The information is
automatically read by the analyzer when a solution pack is installed in the
analyzer.
The traceability certificate for the solution pack is found in chapter 9 of this
manual.
