Terminals 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 TDS exceeds by more than the user-

selectable interval (0 to 400 ppm) from the setpoint

or due to overdosage.

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

activated whenever TDS falls below the setpoint

PROBE (optional) 4-ring potentiometric with built-in temperature sensor

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