Apply for testing of the earth resistance for single equipment energized, not for earth grid;
Application:
u Apply for testing of the earth resistance for single equipment energized, not for earth grid;
u Measure leakage current and Neutral Current can be also.
Product Features
u Neither else earth leads nor cutting off the existing earth leads, the earth resistance of the equipment can be measured directly
u Besides of the earth resistance, leakage current and Neutral Current can be tested
u The max.resolution: 0.001Ω for resistance, 0.1mA for current
u Auto range, data hold, alarm presetting
u Large Jaws,45mm×32mm
u Data Logging and recall
u One second per test
u Marked for CE,ETL,CAT II 600V
