The AEMC 6503 (2126.52) Analog Hand-Cranked Auto-Ranging 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.

The AEMC 6503 (2126.52) Analog Hand-Cranked Auto-Ranging Megohmmeter has an auto-ranging feature which expands the scale by ten times and almost doubles the scale length. When the pointer reaches near the end of scale, the auto-ranging feature activates and returns the pointer to the beginning of the scale with the '10x' red LED indicator on. This unit has three test voltages for insulation resistance testing of 250, 500, and 1000 volts. Test voltages are generated in full across the entire measurement range.
