It is also possible to programme:
-
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
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.

This makes it possible to set the maximum flow offered by
the pump, and the programmed mode (% or frequency) is
used as the standard unit of measurement when displaying
the flow. Changes can be made by pressing the
key,
then using the
keys to set the new value. Press
