Megohmmeter (Hand-cranked, 500V, Resistance, Continuity) Replacement for Cat #1326.01
The Model 6501 and 6503 Megohmmeters are compact, self-contained, hand-cranked True Megohmmeters ® . These practical and dependable instruments are designed for a broad range of plant and field service applications, such as acceptance testing and preventive maintenance of wiring, cables, switch gear 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.
A 600V voltage measurement is provided to perform safety checks to confirm that the sample is fully discharged and not connected to an energized circuit.
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 regulated circuit, these megohmmeters provide a very stable resistance reading.
These analog instruments have 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. An amber (6501) or green (6503) LED on the front panel illuminates when the proper crank speed is attained, indicating the presence of the selected output.
