Paragraph 3 – Proportional dosing for the Redox (O.R.P.) measurement
Programming Operation
The pump measures and controls the Redox value of a solution, by
programming the following parameters: set-point, set-point type,
proportional band and alarm band.
Set-point type: maximum
0

which, if the measured Redox value does not reach the set-point, an
alarm signal is activated.
- Activation / deactivation of the calibration procedure
