3. Turn the below potentiometer (6) first of all anticlockwise (max. 20
turns) until the control lamp signals "covered".
Mode A (overfill protection) = control lamp lights
Mode B (dry run protection) = control lamp extinguishes
If this condition is already reached, you can continue with the next
step.
4. Turn the potentiometer (6) very slowly (due to the damping) clock-
wise until the control lamp signals "uncovered".
Mode A (overfill protection) = control lamp extinguishes
Mode B (dry run protection) = control lamp lights
5. Turn the potentiometer (6) clockwise according to the following
chart.
6. The probe is now ready for operation.
Sensitivity
Standard very sensitive
additional turns Dielectric constant >2
= 2 turns Dielectric constant >1.5
= 1 turn
Tab. 1: Number of additional turns for the potentiometer (6)
Note:
With the measurement of products with very low dielectric values, the
number of turns can be reduced up to 1 according to the chart.
This setting is too sensitive with conductive, adhesive products.
Note:
When placing the housing cover, make sure that the inspection glass
is above the signal lamp of the electronics module.
