40 GOSSEN METRAWATT GMBH
16 Characteristic Values
1)
The device leakage current step of the test sequence is executed by means of
differential current measurement for testing per DIN VDE 0751.
2)
As of 25 mA: shutdown by residual current measurement within 100 ms
3)
Measured value P and calculated value S are compared and the smaller of the two is displayed.
4)
Measuring circuit becomes highly resistive, indication at display
5)
For DIN VDE 0701/0702: 2 kΩ, for DIN VDE 0751: 1 kΩ
6)
This measuring range with DIN VDE 0751 only
