Manual calibration
Perform a manual calibration for sensors that have not previously been
calibrated with the analyzer using the calibration values stated on the sensor’s
Calibration Certificate. Refer to the sample in Figure 3–18.
1. Change the values for Cal0 , T0 , Cal2nd , T2nd and pATM according
to the values shown in the Calibration Certificate. Refer to Figure
3–20.
