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

*Full-scale value of insulation resistance is defined according the following equation:
R = 1GΩ * U [V] (if U
FS test
For insulation resistance value under 5 kΩ the instrument will desplay the value 0 Ω.
DC test voltage:
