POS calibration
From Bioblast
DatLab converts the raw signal to oxygen concentrations by applying conversion factors determined during a POS calibration comprising an air calibration and a zero calibration. For each gain a different set of calibration values is necessary. Frequently, assumed hardware problems turn out to be a simple calibration problem. This can easily be detected by observing the Raw signal. Please see [MiPNet12.08]
Dynamic POS calibration = Calibration of the sensor response time.
Static POS calibration Two-point calibration of the polarographic oxygen sensor.
