Direct method - Ground conductor current measured using ammeter on the ground con-
ductor
1 Measuring device
2 Inverter
8 Isolated setup of test piece
9 Measuring line
Differential current method - Ground conductor current measured using an ammeter on
the N and L conductors
As with an FI switch, the currents between the outer conductor (L) and the neutral conduc-
tor (N) are compared using a converter. The difference is displayed.

The ground conductor leakage current must not exceed the limit value of 3.5 mA during
this measurement (direct or differential current method) **).
**) These requirements comply with DIN VDE 0701-0702 and ÖVE/ÖNORM E8701-1. Also
refer to the applicable requirements and standards in your country.
