The AEMC 6505 5000V Megohmmeter Insulation Resistance Tester features presentation and calculation of Polarization Index (PI) and Dielectric Absorption Ratio (DAR). Displays insulation resistance, test voltage, and the leakage current. At the conclusion of the test, capacitance of the sample and discharge voltage present at the leads is displayed. Operated by AC line power or rechargeable battery system. Performs insulation, voltage, and capacitance measurements.
