  • continuous indication of insulation resistance or leakage current,
  • automatic discharge of capacitance of tested object after the insulation resistance measurement,
  • acoustic signaling of five-second periods to facilitate obtaining time characteristics,
  • measured test times T₁, T₂ i T₃ to measure one or two absorption coefficients in 15, 60 and 600 s,
  • indication of actual test voltage during the measurement,
  • protection against measuring live objects,
  • two and three-lead measurement method,
• Continuity measurement of protective and equipotential conductors according to EN 61557-4
• with the >200 mA current.
• Leakage current measurement.
