Leakage Current Tester 92-4A, -4D, -4E, -4G
BASIC TEST MODES
VI.vii Measuring of contact currents according EN 60598
The measuring of the contact current is carried out according the network
shown below. The contact current have to observe the values predefined
in the EN-standard. A detailed description of the prerequisites for the
measuring contains the EN-standard (see above).
Measurement circuit according EN 60990-1 Fig. 3/4 or 3/5.
