The Digital/Analog Megohmmeter Model 5050 is the latest design in 5000V insulation testers. Features include automatic calculation and presentation of the Dielectric Absorption Ratio (DAR), Polarization Index (PI) and Dielectric Discharge (DD). The Model 5050 displays the test voltage, insulation resistance and the leakage current during the test. Capacitance of the sample and discharge voltage present at the test leads are displayed at the conclusion of the test. This meter is designed with the highest level of built-in safety features. The Model 5050 can be operated from an internal rechargeable battery or from AC line power.Includes:Extra large classic tool bagOne red, one blue and one black lead with integral 5kV rated hippo clipOne jumper lead for use with guard terminal115V power cordRechargeable batteryUser manualFeatures:True MegohmmeterTest voltage combination of 500V, 1000V, 2500V and 5000VInsulation measurements from 30kΩ to 10TΩAdjustable and programmable test voltage (40 to 5100V)Automatic calculation of DAR, PI and DD valuesDirect measurement and display of Capacitance and Leakage CurrentDisplay resistance, test voltage and run timeProgrammable test run times and PI ratio timesSmooth and Alarm functionsAutomatic test inhibition if live sample (>25)Automatic discharge and display of discharge voltageLarge dual-display with time, voltage and measurements shownRugged dual wall weatherproof field caseDesigned and built to IEC safety standardsEN 61010-1, 600V Cat.
