(4): Above 500 Hz, the small display indicates "- - - -" and the main display gives only a rough indication of the peak
value of the measured voltage.
 Measurement category: 1000 V CAT III or 2500 V CAT I (transients   2.5 kV)
7.2.2. INSULATION RESISTANCE
 Method: Voltage-current measurement per IEC 61557-2
 Nominal output voltage: 500, 1000, 2500, 5000 Vdc (or adjustable from 40 V to 5100 V)
 Adjustment step in variable mode: 10 V from 40 V to 1000 V
 Off-load voltage:   1.02 x Un ± 2% (Un ± 2% in variable mode)
 Nominal current:   1 mAdc
 Short-circuit current: < 1.6 mA ±5%
 Charging current into capacitive component: 3 mAdc approximately when starting measurement
 Maximum acceptable voltage during measurement: Upeak = (1.1 + dISt) Un + 60V
