Make Complete Diagnostic Tests of Transformers, Cables, Motors and Other Equipment z PI and DAR display Measurement time PI: Polarization Index DAR: Dielectric Absorption Ratio The PI and DAR values which are used as an evaluation standard for insulation are automatically calculated. With the insulation resistance measurement start point as reference, the calculation is performed as follows, using two resistance values obtained at a prescribed time interval.
