The AEMC Model 5070 is a robust, weatherproof 5000V true megohmmeter designed for insulation testing in field environments. It features a large graphic display with a five-line alphanumeric screen and real-time graphical plotting of measurement data. The device offers selectable and programmable test voltages ranging from 40V to 5100V, with fixed options at 500V, 1000V, 2500V, and 5000V. It supports programmable temperature correction, automatic step voltage testing with up to three profiles of five steps each, and measures insulation resistance from 30 kΩ to 10 TΩ. Additional capabilities include automatic calculation of DAR, PI, and DD values, as well as measurement of resistance, test voltage, leakage current, and capacitance. The megohmmeter features automatic discharge, safety interlocks for live voltage detection, and is powered by rechargeable NiMH batteries, which can be charged while in use. It includes a 128KB memory for storing over 1500 test results, remote operation via RS232, and compatibility with DataView software for data management, analysis, and report generation. Certified to IEC safety standards, IP53 rated, and suitable for professional insulation testing applications.
