Clamp-on Tester 30031A/30032A (Leakage Current)

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.


See Yokogawa's Leakage Current Test Equipment Brochure and both models' instruction manuals for complete details on measuring leakage current.

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)
