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
SETPOINT RANGE From 0 to 1999 ppm (mg/L)
