    Measurement of leakage current

     

    Range Resolution Accuracy
    0…ILmax m, µ, n [A] Calculation based on resistance measures

    · ILmax – maximum current at short circuit of leads,
    · resolution and units result from the measurement range of individual insulation resistance.

    Step voltage insulation resistance measurement

    Target voltage Measurement voltage sequence
    1 kV 200, 400, 600, 800, 1000 V
    2,5 kV 0,5, 1, 1.5, 2, 2,5 kV
    5 kV 1, 2, 3, 4, 5 kV

    · duration of each "step" adjustable from 30s to 5mins
    · measurement result for each voltage step is stored in memory

    Capacity measurement

    Range Resolution Accuracy
    1...999 nF 1 nF ±(5% m.w. + 5 digits)
    1,00...49,99 µF 0,01 µF ±(5% m.w. + 5 digits)

    · Capacity measurement result is displayed after the RISO measurement

    DC and AC voltage measurement

    Range Resolution Accuracy
    0.0...29,9 V 0,1 V ±(2% m.v. + 20 digits)
    30,0...299,9 V 0,1 V ±(2% m.v. + 6 digits)
    300...600 V 1 V ±(2% m.v. + 2 digits)
     

    The acronym “m.v.” stands for a “measured reference value”.
