ProductDescription : Product description
The ZC-8 grounding resistance tester can be used to measure the grounding resistance of various
power systems, electrical equipment, communication towers, high-rise buildings and other
grounding systems. It can also measure the resistance of low-resistance conductors and the resistivity of soil.

Measurement of Model ZC29B
Model ZC29B can measure soil resistivity. Insert four underground probes (two of which are
self-matched) in the measured area along a straight line. The distance between each other is "I",
and the depth of the rod is "b", which should not exceed 1/20I. The measured soil resistivity: p=2πIR

R-the reading of the meter
I-the distance between the probe and the probe
p-Soil resistivity in the area
The resistivity obtained above can be approximated as the average soil resistivity in the area between the buried rods.

Connect the two E-terminal button wires on the meter to the grounding body to be tested to
eliminate the additional error caused by the resistance of the connecting wire during the measurement.
