AEMC 1250N megohmmeter - 1000V hand-crank analog

The AEMC 1250N 1000V 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 1250N 1000V Megohmmeter has three test voltages for insulation resistance testing: 250V, 500V and 1000V. Test voltages are generated in full across the entire measurement range.

The AEMC 1250N Megohmmeter incorporates a built-in, sealed alternator and constant DC voltage circuit to provide a very stable resistance reading. The megohmmeter is ruggedly built, with a safety-yellow cast aluminum case, aluminum lid and polycarbonate front panel. The AEMC 1250N Megohmmeter is designed for harsh, heavy-duty use. An O-ring seal between the front panel and case protects the unit against water and dust. The crank folds against the unit for storage.

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 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 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 1250N 1000V Megohmmeter has four terminals including a guard terminal and an instrument ground terminal for user safety.
