Information for the tester
Earthing/grounding resistance (R
Measuring method: Current-voltage measurement with sonde as per
IEC 61557-5
Nominal voltage: 101 - 253 V sinusoidal
Frequency range: 46 - 65 Hz
Permissible overload: U = 600 V (Measurement is not started)
eff
Electrical safety is given during and functional safety after overload.
