Tips:
 Use the Z
I
function for loop measurements.
 Preload conditions can cause the RCD to trip.
 An RCD with a nominal fault current of 10 mA will trip.
 To test loop impedance in a circuit with a 10 mA RCD, see Loop Impedance Test with 10 mA
RCD section.
 Interference meter shows on the display.
To measure loop impedance no trip mode for L-PE:
1. Select the Z
I
function for Loop No Trip. See Figure 11.
2. Select input.
3. Zero the test lead resistance offset.
4. Turn on or turn off Zmax.
