insulating resistance measurement between secondary side and the equipment body
3.BENNING BENNING 750 A
2 for the stated insulating resistance measurements for protection class II
- not all parts are measured completely (e. relays semiconductor components impedethe transmission electricity) or
- the measurements have been terminated with negative result for devices containingheating elements,
th altern ative leak rre rem etho applied!
In this case, necessary use the direct differential current measurement method.
3 Additional tests for devices with secondary output voltage, e. insulating resistance measurement between secondary and primary side

4 When exceeding the limiting value (protective conductor current), has checked whether other limiting values have observed due product standards manufacturer specifications. isolating transformer, chargers, converters, mains supply units:
1. contact current measurements the secondary voltage outputs (except III)
4.g.g. measurement the open-circuit voltage output voltage
