Description
M-140HC Mini Digital Clamp Tester (CE)
The M-140HC Mini Digital Clamp Tester is designed for measuring AC leakage current, AC line current, and phase current in high-voltage CV/CVT cables. Its 40 mm jaw opening supports clamp-on measurements, including phase current detection at shielded cable sections with grounding connections.
The tester provides AC current measurement up to 320 A, with dedicated CVT and CV phase current ranges of 16 A and 48 A, respectively. It features a 3200-count digital display, data hold, auto power-off, and a length display function for high-voltage cable measurements.
