Key features

  • Insulation testing at 50 V, 100 V, 250 V, 500 V and 1000 V, up to 200 GΩ at 1000 V
  • Stabilised insulation test voltage, maintained within -0% +2% (industry standard 10-20%)
  • Polarisation Index (PI, 10 min / 1 min) and Dielectric Absorption Ratio (DAR, 60 s / 15 s or 60 s / 30 s)
  • Timed testing and insulation test lock
  • PASS / FAIL indication on limit alarms
  • Leakage current display
  • Single auto-ranging continuity range from 0.01 Ω to 1 MΩ, with 200 mA or 20 mA test current and automatic bi-directional testing
  • True RMS AC and DC voltage measurement to 600 V with automatic frequency display
  • Analogue arc plus dual digital display (result and test voltage, leakage current, frequency or test mode)
  • Live circuit detection inhibits insulation testing above 25 V, 30 V, 50 V, 75 V or 100 V (default 50 V), even if the fuse has failed
  • Over-moulded case sealed to IP54, including battery and fuse compartment
  • Runs on 6 AA alkaline or NiMH rechargeable cells
