POINT
If less than one turn of the adjustment was observed
between the sensing element covered and uncovered,
the sensor is not generating enough signal. Consult
the factory for further options.
7. Turn the adjustment back counterclockwise (CCW) one
half the number of turns that were counted.
8. Record number of turns and save for future calibration
reference
Calibration is now complete.
4.3 Calibration in Insulating Material [Vertical Mount]
This 20-turn potentiometer does not have a
mechanical stop. Turn 20 times to assure that you are
at the extreme end. No damage will occur.
The LED (on) indicates that the relay is energized or in
normal condition (not alarm).
1. Set the level to a point on the active section of the
sensing element where control is desired (3 inches [76.2
mm] of coverage minimum).
See Figure 4-3.
2. Start from the full counterclockwise (CCW) position.
Turn the setpoint adjustment clockwise (CW) until the
relay just operates (LED changes states).
If dielectric constant or conductivity of material
changes, point of operation may change. Consult
factory.
Calibration is now complete.
