Clamp-on Tester 30031A 30032A

The 30031A and 30032A are small leakage current clamp meters by Yokogawa. The 30031A Clamp-On Leakage Current Tester has a sharp low pass filter function, and the 30032A Clamp-On Current Leakage Tester is capable of measuring from 1 mA AC. Both models of leakage current test equipment use mean value as their leakage current measurement method of detection and rms value calibration.

Temperature Coefficient	0.05% of range /°C or less (within the ranges of 0-18° and 28-50° for measurement of 0-50 A)
Note	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 tensional 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 EN 61010-2-032 (CAT III 300V, pollution degree2)
