Menu index “3A2” Frequency output proportional to pH measurement (FWM PH)
The frequency output (Open collector circuit) can be used to control and guide the dosing of a remote
system in proportion to the pH measurement.
•
Menu index “3A3” Current output proportional to pH measurement (OUT mA PH)
Note:
The value set under the
HOLD mA
item is automatically generated by the instrument when a functional Hold
is present, for example due to a lack of water Flow Alarm or an enabled Voltage Input.
•
Menu index “3A4” PH ALARMS
Note:
The
Holding Range
and
Holding Time
items must be used together.
The indicated function controls the chemical measurement at a constant value for long periods of time. This alarm
can help to prevent incorrect dosing as a result of damaged probes.
