AC Leakage

●Can measure leakage currents of 1 mA, which is useful for checking

the insulation of low-voltage circuits and electrical components.

●Can measure a broad range of currents from leakage currents

(at a resolution of 0.001 mA) to load currents up to 60 A.

●Typical influence (on the current value of an adjacent cable) from an

external magnetic field is 0.0005%.

●Durability of clamp: More than 50,000 opening/closing events

●Twice the torsional strength of Yokogawa M&C's earlier model clamps

●The clamp lever is lengthened by 30%, enabling smooth opening/closing

of the clamp even for thick cables of 40mm in diameter.

●Approved for conformity to safety standards EN 61010-1 and
