Terminal can be configured as normally open or

normally closed (isolated output Max. 2A, Max. 240V,

resistive load, 1,000,000 strokes). The alarm is

activated if conductivity exceeds by more than the user-

selectable interval (0 to 2.0 mS/cm) from the setpoint

or due to overdosage

Relay (115 to 240V, Max.2A,1,000,000 strokes) is

activated whenever conductivity falls below the setpoint

CALIBRATION Through "ZERO CAL" and "SLOPE CAL" trimmers
