The Model 6527 is a portable multi-range True Megohmmeter® capable of measuring insulation resistance from 1kΩ to 4000MΩ. It has three user selectable test voltages of 250V, 500V and 1000V. The Model 6527 is also a multimeter that features an AC/DC voltmeter function capable of measuring up to 600VAC and 1000VDC, continuity test function with audible beeper for resistances under 35Ω, and an overload protection of 600Vrms. In addition, it can measure resistance up to 400kΩ.
The TEST button has an associated locking feature for continuous tests up to 15 minutes, eliminating the need to manually hold down the button. This lightweight, easy-to-use megohmmeter can be used for most commonly performed insulation tests, such as on cables, switch gears, motors, DC generators, power tools and small appliances.
