OPERATING MANUAL MPI-530-IT version 1.06
The way of making short circuit loop measurements is described in point 3.4.1. Operating voltage
range: 95 V … 440 V.
3.5 Measurement of resistance to earth
3.5.1 Measurement of resistance to earth using 3p method
The three-lead measuring method is the basic type of resistance-to-earth measurement.
Disconnect the tested earth elec-
trode from the system of the object.
The current electrode (driven into earth) should be connected to H socket of the meter.
The voltage electrode (driven into earth) should be connected to S socket of the meter.
The earth electrode being tested should be connected to E socket of the meter.
The tested earth electrode as well as current and voltage electrodes should be located along one
line and in the relevant distances, in accordance with the rules of earth measurements.
