The AEMC 6501 [2126.51] Hand-Cranked Megohmmeter is a compact, self-contained, hand-cranked True Megohmmeter. This practical and dependable instrument is designed for a broad range of plant and field service applications, such as acceptance testing and preventive maintenance of wiring, cables, switchgear and motors. The easy hand-cranked operation provides a steady, DC voltage output across the entire range for consistently reliable readings. In addition to insulation resistance testing at 500V, the Model 6501 also permits resistance testing to 500kΩ and continuity testing to 100Ω. The 600V test voltage range is to perform safety checks to confirm that the sample is fully discharged and not connected to an energized circuit.
