Application:Hazards due to improper earth / ground happen around us everyday. Systems are becoming more and more complex and faults in any system are unavoidable. Every electrical equipment, appliance or network must be properly earthed to allow a low resistance path for dissipation of leakage current into the earth. MECO Clamp-On Earth / Ground Resistance Tester can measure accurately within a few minutes the ground resistance & AC current (load & leakage) of all types of installations by just clamping to the grounding lines without disconnecting the circuit or driving auxiliary electrodes.
