Programming
Operation
The pump measures and controls the pH of a solution,
programming in sequence: set-point, set-point type,
proportional band and alarm band.
the O.F.A. (Over Feed Alarm) time in minutes, or rather
a time beyond which an alarm signal is triggered if the
pH value does not reach the set-point.
The measurement resolution (1 or 2 decimal points)
Deactivation/activation of the calibration procedure
Manual temperature value in ºC (default) or ºF
The maximum frequency can be modified during
operation, by pressing the keys at the
same time to increase the flow, or the
keys to decrease it.
It is also possible to program:
