The AEMC 5060 Features include presentation of the Dielectric Absorption Ratio (DAR) and automatic calculation, Dielectric Discharge (DD) and Polarization Index (PI). The Model 5060 will display the test insulation resistance, voltage, and the leakage current while testing. At the conclusion of the test, the Capacitance of the sample and discharge voltage present at the test leads will be displayed. The highest level of safety was taken into consideration when designing this meter. The Model 5060 can be operated from an AC line or an internal rechargeable battery system. It also offers much more functionality because the RS 232 port allows the ability to run the test from the PC and configure the unit from a PC as well. You can also print directly to your printer from the unit.
