AC Leakage Clamp Meter

M-140HC Mini Digital Clamp Tester (CE)

AC Current/Leakage with Hi-Voltage Phase Current Detection


Easy!:Measurale Load Current at high voltage CV/CVT cables with grounding lines for shield phase.
Epoch-Making!:Can measure phase current of CVT cable just by putting CT head on to the conductors as well as CV cable just by clamping CT to the conductors in a lump.
Low Cost!:Can measure line/leakage current in the same manner as ordinary clamp meters.
