mV
: unit for the redox potential
percent
: concentration percentage that can be
derived from the redox measurement
This requires a two-point calibration.

0.0 to 25.0 s
Optimization of measuring value updating
The higher the value of the filter time const., the
slower the measured value is displayed.
