CURRENT RANGE MEASUREMENT (KM 1220)
ETCR Clamp Earth Resistance Tester is widely applied in ground resistance measurement, loop resistance
measurement in fields such as electric power, telecommunications, meteorology, oil field, architecture and
industrial electrical equipment, etc. When measuring ground system with loop, there is no need to disconnect
the ground wire without auxiliary electrode, which means safer and faster. KUSAM-MECO Clamp Earth
Resistance Tester can measure the ground fault which can not be measured by traditional method, can apply in
the occasion where traditional methods are unworkable; KUSAM-MECO Clamp Earth Resistance Tester
measures the integrated value of ground resistance and resistance lead. Tester can measure the leakage
current of ground wire.
