Ground Resistance Tester

The instrument is microprocessor-controlled and is a 2/3/4-wire type for measuring grounding resistance and soil resistivity (ρ) in digital form. It is a grounding resistance / soil resistivity tester capable of measuring both direct current voltage and alternating current voltage. The output voltage is approximately below 50Vrms, and it can be used to test grounding resistances of various equipment such as agricultural equipment, indoor wiring, electrical machinery, etc.
