1. [CAL] to access the sensitivity calibration routine
The Sensitivity calibration is suggested when the readout is very low compared with the DPD test.
This adjustment must be effected when installing the flow cell and Chlorine or D.Ozone sensor after
the stabilization of the readout.
The instrument features two calibration mode: Immediate and Postponed
