5.Set the trip adjust pot to zero, fully counterclockwise (fully ccw).
6.Adjust the zero adjust pot so that the Red LED just does illuminate. This is a 25 turn pot. If the green LED is on, turn the pot counterclockwise (ccw). If red LED is on, turn the pot clockwise (cw).
7.Toggle the zero adjust pot back and forth until the switching point is well defined. Leave the Red LED illuminated.
8.Raise the level of the liquid to be detected until the probe/sensor tips are submerged and wet (covered).
9.Set the trip adjust pot to 100 (fully cw).
10.Adjust the span adjust pot so that the Green LED just does illuminate. This is a 25 turn pot. If the Green LED is on, turn the pot cw. If the Red LED is on, turn the pot ccw.
11.Toggle the span adjust pot back and forth until the switching point is well defined. Leave the green LED illuminated.
12.Adjust the trip adjust pot to 80 and the calibration is complete. Setting this pot to 80 gives an approximate equal trip time from wet to dry and from dry to wet. Setting this pot closer to zero will speed up dry to wet trip time and slow down wet to dry trip time. Setting this pot closer to 100 will slow down the dry to wet trip time and speed up wet to dry trip time.
