The AEMC 6503 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 Model 6503 has three test voltages for insulation resistance testing: 250V, 500V and 1000V. Test voltages are generated in full across the entire measurement range.

Incorporating a built-in sealed generator and constant DC voltage circuit, the AEMC 6503 megohmmeter provides a very stable resistance reading.

This analog instrument has a unique auto-ranging feature which expands the scale ten times. When the pointer reaches near the end of scale, the auto-ranging feature activates, returning the pointer to the beginning of the scale with the x10 green LED indicator on.

Insulation resistance is indicated with a rugged taut-band meter movement on a logarithmic scale. The indicator scale is large and easy-to-read, and has direct reading on all ranges. An amber LED on the front panel illuminates when the proper crank speed is attained, indicating the presence of the selected output.

The AEMC 6503 includes a complete set of test leads, clips and a test probe to perform any test.Features
