Product Description:
space
space 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 is 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 system or from an AC line power.The Model 5050 offers additional functionality in that an RS-232 port provides the ability to configure the unit from a PC and run the test from the PC. Test reports can be generated directly from the instruments to a printer or through the PC using the DataView® graphing and analysis software.
