The AEMC Model 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, 250 V, 500 V and 1000 V, for insulation resistance testing. Test voltages are generated in full across the entire measurement range. A 600 V test voltage range is provided to perform safety checks to confirm that the sample is fully discharged and not connected to an energized circuit.

The AEMC Model 6503 megohmmeter 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 red 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 a direct reading on all ranges. A green LED on the front panel illuminates when the proper crank speed is attained, indicating the presence of the selected output.

The AEMC Model 6503 megohmmeter ships complete with:

  • Set of test leads
  • Clips
  • Test probe
