The AEMC 6527 Digital Handheld Megohmmeter is a portable multi-range true megohmmeter designed to measure insulation resistance from 1 kΩ up to 4000 MΩ. It offers three user-selectable test voltages: 250V, 500V, and 1000V. This device also functions as a multimeter with AC/DC voltage measurement capabilities up to 600 VAC and 1000 VDC, a continuity test with an audible beeper for resistances below 35Ω, and overload protection of 600 Vrms. It can measure resistance up to 400 kΩ. The TEST button features a lock for continuous testing up to 15 minutes, removing the need to hold the button manually. This lightweight and easy-to-use megohmmeter is suitable for testing insulation in cables, switchgear, motors, DC generators, power tools, and small appliances.
