  • automatic measurement in sockets with the UNI-Schuko adapter with possibility of configuring pairs of measured cables,
  • continuous indication of insulation resistance or leakage current,
  • automatic discharge of capacitance of tested object after the insulation resistance measurement,
  • acoustic signalling of five-second periods to facilitate obtaining time characteristics,
  • measured test times T1, T2 i T3 to measure one or two absorption coefficients in the 1… 600 sec. range,
  • indication of actual test voltage during the measurement,
  • protection against measuring live objects,
  • three-lead measurement.
