The measurement can be taken on the battery charging system (via an adapter lead) or in
the distributor. If taking the measurement in the distributor, ensure that there are no live
conductors in the immediate vicinity, or that there are no other consumers depending on
the same circuit.
Direct method - Ground conductor current measured using ammeter on the ground con-
ductor
1 Measuring device
2 Battery charging system
8 Isolated setup of test piece
9 Measuring line
Example: Measuring ground conductor current th-
rough ground conductor directly on the battery char-
ging system
Differential method - Ground conductor current measured using an ammeter on the N
and L conductors

Example: Measuring ground conductor current directly
on the battery charging system using the differential
method
As with an FI switch, the currents between the outer conductor(s) (L) and the neutral con-
ductor (N) are compared using a converter. The difference is displayed.
The ground conductor leakage current must not exceed 0.75 mA during this measurement
(direct or differential 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.
