4-Pole Selective Earth Resistance Measurement with Current Clamp
The R
A
4-pole Selective Earth Resistance Measurement with Current Clamp procedure is
useful for the resistance measurement of different parallel sections of an earth/ground
system.
1. Select function 4 POLE . See Figure 7.
2. Connect test leads.
Connect terminals E/C1 and ES/P1 with the supplied safety test leads (1.5 m) to
the earth electrode to be measured. Place two ground stakes in earth/dirt.
Minimum distance between earth electrode (E/C1), probe (S/P2) and auxiliary
earth (H/C2) should be a minimum 20 m. The test lead eliminates the influence
of the test leads.
Connect stakes with 25 m and 50 m wires to H/C2 and S/P2 as shown.
Connect current clamp with adapter cable as shown.
3. Push START.
indicates that measurement is in progress. For continuous
measurement, continue to push the START button.
4. indicates completed measurement. The result is kept on display until a new
measurement is started or the rotary switch is turned.
