The control of the pumps in the pH and Redox scale is carried out through the PWM
function.
The proportional band is fixed on the values pH0.8 and Redox = 120 mV

Proportional dosing pH-/pH+
The instrument allows the chemical measurement to be controlled and modified through the
pH- and pH+ Set Point automatically; adjusting the dosing through the pH-/pH+ motor
controlled in Proportional Time.
The dosing below is obtained by setting the following parameters:
Set point pH- = 8.10 pH
Set point pH += 6.90 pH
Proportional Band = 0.80 pH
