The 4-20mA proportional analogue outputs are related to the measurements
in real time, in order to drive remote equipment such as data loggers, PLCs
or graphic recorders or other equipment suited to processing a remote mA
signal.
Select the value corresponding to 4 and 20 mA based on Setpoint 1.

Select the Set point value to control the metering pump or other equipment
suited to processing the mA signal.
The mA setpoint is set (default) for
operations in ACID mode, the output
is active when the measured value is
higher than the selected setpoint, the
connected pump meters out an acid
The mA setpoint is set (default) for
operations in DIRECT mode: if the
measured value is lower than the
selected setpoint, the connected
pump meters out chlorine (Oxidising
