Portable Earth Test Equipment 200Ω Earth Resistance Tester ORGR-D
ORGR-D Earth Resistance Tester
I.Product introduction
ORGR-D earth resistance tester uses an internal DC/AC converter to convert DC into AC low-frequency constant current, which forms a circuit through the auxiliary grounding electrode C and the tested object E. An AC voltage drop is generated on the tested object, amplified by the AC amplifier through the auxiliary grounding electrode P, and then detected and displayed on the meter head. With the help of a multiplier switch, three different measurement limits can be obtained: 0-2 Ω, 0-20 Ω, and 0-200 Ω.
