Material correction factor
If the object in question is not metal or water, the sensing range is
reduced. The reduction factors for the different materials are shown in the
table below.
Sensitivity adjustment
Capacitive proximity detectors are fitted with a 14-turn potentiometer. The
potentiometer must be adjusted to suit most applications. Turn in a
clockwise direction to increase sensitivity. From the original setting of
0.7-0.8 x Sn (Sn = nominal sensing range), the nominal sensing range is
reached after 2-3 turns. This leads to non-linearity of the curve and
hypersensitivity, which may cause the sensor to lock. If this occurs,
decrease sensitivity by turning the potentiometer 2-3 turns anticlockwise.

Temperature
Capacitive proximity detectors operate within a temperature range of -
5°C to +70°C. The maximum sensing distance deviation is ± 10 % when
the adjusted sensing distance at +20°C is no greater than the nominal
specified distance (taking the material reduction factors into
consideration).
Example of setting procedure
A liquid (water, for example) is to be scanned through a separating wall
by a sensor. The separating wall is made of glass or plastic, with a
maximum thickness of 4 mm. The thickness in mm should be between 10
and 20% of the adjusted sensing distance, but always less than 4 mm.
The face (active surface) of the sensor is bonded to the glass or plastic
wall. The vessel is filled with water until approx. 75% of the active surface
of the sensor is covered. Turn the sensor potentiometer anti-clockwise (to
reduce the sensitivity) until the LEDs and the output signal turn off.
Turn the potentiometer clockwise (to increase the sensitivity) until the
LEDs and the output signal light up.
Using the calibration process described ensures that the sensor does not
detect the wall or the water residue on the wall.
It only operates once the liquid has reached the 75% level described
above.
