also be observed.

The measurement voltage may be an AC or a DC voltage.
The open circuit voltage may not exceed 24 V or fall below 4 V.
The measurement current within the measuring range between 0.2  and 1.99  may
not fall below 0.2 A.
The value of the measured voltage from the measuring instrument must correspond
to at least the rated voltage of the device to be tested against grounding, but no less
than 500 V DC voltage
The measurement current must be at least 1 mA (this corresponds to a load resis-
tance of 0.5 M).
The effective inner resistance of the ground conductor current measuring device may
be a maximum of 5 . (With higher resistances, measures must be taken to prevent
the occurrence of hazardous contact voltages.)
The measuring range must comprise at least the values from 0.25 mA to 19 mA.
The inspection facility must assess the measured current to be an effective value re-
gardless of the waveform.
The effective inner resistance of the contact current measurement instrument must be
1 k to 2 k.
If the current test circuit is accidentally connected to a voltage up to 120% of the nom-
inal grid voltage, the user must not be endangered and the test circuit must not be
damaged.
The inspection facility must assess the measured current to be an effective value re-
gardless of the waveform.
