Calculating Calibration
Parameters and QC Rule
The system provides two calibration methods: linear calibration and nonlinear
calibration. Linear calibration includes one-point linear calibration, two-point linear
calibration and multi-point linear calibration. They are mainly used for tests
determined by colorimetry. Nonlinear calibration includes Logit-Log 4P, Logit-Log 5P,
Exponential 5P, Polynomial 5P, Parabola and Spline. They are mainly used for tests
determined by turbidity.
