User Guide

• Set Select

These contacts permit the activation

of a Set Contact relay when the

measured value is lower (connected

terminals) or higher (open termi-

nals) than the user's set value. See

also page 27.

• +4-20 mA

These are the output terminals for connection to a recorder or other

control equipment.

The output current varies from 4 to 20 mA and is proportional to

the measured conductivity value.

• Alarm Contacts

During normal operation these termi-

nals remain closed.

If the measured conductivity level is

not within the tolerance of the set

value, the alarm contact is open.

These contacts act only as a switch.
