Introduction Kyoritsu 4200

This instrument is a digital clamp-on earth resistance tester, and it is used in multi- earthed systems. Can measure the earth resistance by simply clamping around the earthed wires. This instrument also equips AC current function to measure current up to 30A same as our traditional leakage clamp meters. A single earthing cannot be measured. (only for multiple-earthing system)
