Insulation Resistance

Nominal test voltage: 250 V, 500 V, 1 kV, 2.5 kV, 5 kV
Current capability of test generator: >1 mA
Short-circuit test current: 5 mA.
Automatic discharge of tested object: Yes
Measuring Range Riso: 0.12 MΩ up to 999 GΩ*
Display Range
5 - 999 kΩ
1.00 - 9.99 MΩ
10.0 - 99.9 MΩ
100 - 999 MΩ
1.00 - 9.99 GΩ
10.0 - 99.9 GΩ
100 - 999 GΩ
*Full-scale value of insulation resistance is defined according the following equation:
R
= 1GΩ * U

For insulation resistance value under 5 kΩ the instrument will desplay the value 0 Ω.
DC test voltage:
Voltage value: 250V, 500V, 1kV, 2,5kV, 5kV.
Accuracy: -0 / +10 % + 20 V.
