Buy with confidence save and get free and fast shipping

Measures:
  • Earth and differential leakage currents
  • Leakage currents through the earth (PE) conductor
  • Appliance current consumption without interruptions to the circuit

Features:
  • True-rams measurements for accuracy when measuring complex, non-sinusoidal waveforms
  • Mechanical jaw lock to assure accuracy of low current measurements, avoiding disturbance from measured wires and magnetic fields; jaw opening 1. 2 in (30 mm)
  • Selectable filters: low pass 50/60Hz filter to perform measurements on equipment driven by variable frequency drives (VFDs) or affected by high frequency noise, appliance filter to conduct leakage current measurements on appliances and no filter
  • Trace the source of earth leakage currents
  • Identify intermittent GFCI trips without switching equipment off
  • Check a system for an electrical break of insulation where current is flowing to the ground
  • For use where industrial leakage current testing is required
