Earth/Ground Tester Operation Operation The Tester is equipped with a 3-pole as well as a 4-pole resistance measurement that renders measurements of resistances of earthing systems and measurements of the soil resistivity of geological strata. The Tester also makes measurements with an external current transformer, with which a measurement of single resistance branches in interlinked networks (lightning protection and high voltage pylons with cabling) can be performed without separating parts of the system. RA 2-Pole, 3-Pole Measurements To make 2-pole or dead-earth measurements, connect a jumper between terminals H/C2 and S/P2 with the supplied connector cable. Use only the earth electrode and the auxiliary earth electrode. Minimum distance between earth electrode (E/CD1) and auxiliary earth (H/C2) should be at least 20 m. See Figures 3 and 4 and do steps 1 thru 4: 1. Select 3 POLE. 2. Connect the test leads. Connect terminal E/C1 to the earth/ground system to be measured with the supplied test lead and clip (1.5 m). Place two ground stakes in earth/dirt. Note Minimum distance between earth electrode (E/C1), probe (S/P2), and auxiliary earth (H/C2) should be at least 20 m. Connect the stakes with the 25 m and 50 m cable reels to H/C2 and S/P2 as shown in Figures 3 and 4. 3. Push START.  indicates that a measurement is in progress. For a continuous measurement, continue to push the START button. 4.  indicates a completed measurement.

Operation
The Tester is equipped with a 3-pole as well as a 4-pole resistance measurement that
renders measurements of resistances of earthing systems and measurements of the soil
resistivity of geological strata. The Tester also makes measurements with an external
current transformer, with which a measurement of single resistance branches in
interlinked networks (lightning protection and high voltage pylons with cabling) can be
performed without separating parts of the system.

2-Pole, 3-Pole Measurements
To make 2-pole or dead-earth measurements, connect a jumper between terminals H/C2
and S/P2 with the supplied connector cable. Use only the earth electrode and the
auxiliary earth electrode. Minimum distance between earth electrode (E/CD1) and
auxiliary earth (H/C2) should be at least 20 m.
See Figures 3 and 4 and do steps 1 thru 4:
1.

3 POLE
.
2.
Connect the test leads.
Connect terminal E/C1 to the earth/ground system to be measured with the
supplied test lead and clip (1.5 m). Place two ground stakes in earth/dirt.
Note
Minimum distance between earth electrode (E/C1), probe
(S/P2), and auxiliary earth (H/C2) should be at least 20 m.
Connect the stakes with the 25 m and 50 m cable reels to H/C2 and S/P2 as
shown in Figures 3 and 4.
