Description

The AEMC
hand-cranked megohmmeters. They are practical and dependable
instruments 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 rectified DC voltage output across the
entire range for consistently reliable readings.
These megohmmeters incorporate a built-in generator and a con-
stant DC voltage circuit to provide a stable output and give direct
insulation resistance reading.
The Models 6501/6503 have a unique auto-ranging feature which
expands the scale by x10 and almost doubles the scale length.
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 easy to
read.
