• Screwdriver with blade width approx. 4 mm
The rotary switches and adjusting elements for calibration are on the
electronic insert in the housing.
Directly beside these calibration elements are the power connections with
voltages up to 250 V.
Only use a screwdriver which has insulation as far as the blade or else tape
over the terminals with insulating tape before calibration.
Turn on the power supply.
Switching delay can be adjusted between approx. 0.5 s and 20 s.

Select the optimum time for your application.
Accurate adjustment with a free probe is possible:
• Touch the central screw in the electronic insert with the screwdriver.
After a preset time, the Nivocompact switches, the LED goes off
or comes on.
