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.

- The O.F.A. (Over Feed Alarm) time in minutes, a set period of time after
which, if the measured Redox value does not reach the set-point, an
alarm signal is activated.
- Activation / deactivation of the calibration procedure
