8.1 Performing a mounting correction (offset)
The mounting correction corrects a zero offset in the output signal by defining a new
zero point. The zero offset is caused by the mounting position.
Correction range: ±20 % of maximum measuring range
Required tool: Multimeter (ammeter)
1. Screw off the case head cover and pull out the push-on cap.
2. Press [Zero] for approx. 2 s (e.g. with measuring tip of a multimeter).
Mounting correction successful: Control diode lights up for 2 s.
Mounting correction unsuccessful: Control diode blinks 5 times.

- Ensure that the multimeter does not come into contact with the positive
power supply terminal.
Set the multimeter to current measurement.
