Using the Compare function

1. Before starting the insulation test :
Press the COMP button to select the compare value among
100kΩ,200kΩ,500kΩ,1MΩ,2MΩ,5MΩ,10MΩ,20MΩ,
50MΩ,100MΩ,200MΩ and 500MΩ.
2. If the measured value is greater than the selected compare
value, the green Pass indicator will be turned on.
Measuring PI/DAR
PI(Polarization Index)=R10-min/R1-min
DAR(Dielectric Absorption Rations)=R1-min/R30-sec
where
R10-min : the insulation resistance measured at the 10 minute
after pressing the TEST button.
R1-min : the insulation resistance measured at the 1 minute
after pressing the TEST button.
R30-sec : the insulation resistance measured at the 30 second
after pressing the TEST button.
