Leakage current reading
Range | Resolution | Accuracy |
0...Ipmax | depending from range | -ΔI-, +ΔI+ |
Ipmax - maximum converter’s current equal to 1,2 ± 0,2 mA,
ΔI-, +ΔI+ - current reading accuracy calculated from the resistance reading using the formulas:
UISO - test voltage
R - displayed value of the insulation resistance
ΔR - resistance measurement accuracy defined for the measurement
