7.2.3. INSULATION RESISTANCE
Method: voltage-current measurement as per IEC 61557-2 or per DIN VDE 0413 Part 1/09.80.
Nominal output voltage:
Nominal current: 1 mA
Short-circuit current: < 1.6 mA
Maximum acceptable AC voltage: (1.1 + dISt) x Un + 60 V
Measurement ranges:
500 V : 10 k ... 1.999 T
1000 V : 10 k ... 3.999 T
2500 V : 10 k ... 9.99 T
5000 V : 10 k ... 9.99 T
Var 40 V ... 5100 V: to be interpolate between the fi xed values above.
