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. Product parameter Model: ZC-8-1 Size: 116X172mm Specification: 10-100-1000 Measuring range: 0-1000Ω Minimum graduation value: 10Ω
