- 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 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.
