- Hand-cranked analog meter has a 500V test voltage for measuring insulation resistance to 200 megohms, and also measures low-resistance to 500 kilohms.
- Auto-ranging meter automatically selects the appropriate operating range for measurements.
- Measures AC and DC voltage to 600V for confirming that the circuit under test is fully discharged and not connected to a live circuit.
- Residual voltage is automatically discharged from the circuit under test upon completion of a measurement.
- Meets EN safety standard 61010-1 and is rated for CAT III installations to 300V and CAT II installations to 600V.
The AEMC 6501 hand-cranked analog megohmmeter is an auto-ranging
insulation tester with a 500V test voltage for measuring
insulation resistance to 200MΩ to indicate the condition of
windings or cables in motors, switchgears, electrical
installations, and other insulated equipment, and it also
measures low-resistance to 500kΩ and AC and DC voltage to 600V
for confirming that the circuit under test is fully discharged
and not connected to a live circuit. Powered by a hand-cranked
generator, the meter reaches the test voltage at approximately
140rpm, illuminating an LED to indicate that the necessary test
voltage and crank speed are present for a valid reading. When
measurement is complete, residual voltage is automatically
discharged from the circuit under test. The meter has an analog
scale with a needle pointer. This auto-ranging meter
automatically selects the appropriate operating range for
measurements. When the pointer reaches about 90% of the scale
capacity, the auto-range triggers, resetting the needle to the
beginning of the scale and lighting an LED to indicate that
subsequent readings should be multiplied by ten. The meter is
rated for category (CAT) III installations to 300V, which covers
energy-consuming equipment connected to a fixed installation,
including household, office, and laboratory appliances and CAT II
installations to 600V, which covers energy-consuming equipment
connected to a fixed installation, including household, office,
and laboratory appliances. It comes with a set of test leads, a
set of alligator clips, a test probe, a soft carrying case, and
instructions. Megohmmeters are commonly used for electrical
maintenance and testing in industries such as HVAC,
transportation, manufacturing, mining, and utilities, among
others.

.Megohmmeters, also called insulation testers, are electrical
test meters that measure resistance to the flow of current in an
electrical component or circuit and check the continuity of an
electrical circuit to detect electrical problems such as degraded
insulation and improper circuit connections in equipment, wiring,
and power supplies. Resistance is an indicator of the overall
condition of the device being tested. Megohmmeters have an
internal power supply, such as a battery or a capacitor, which
supplies a test voltage to a circuit or component that is turned
off. Test leads are connected in a series to the tester and the
circuit or device being tested. The meter calculates the
difference in voltage between the leads and measures the
resistance. Most megohmmeters have two terminals for test lead
attachment. The two-terminal, or two-wire, measurement method
includes the resistance of the circuit or device being tested and
the resistance of the test leads, and generally provides
sufficient accuracy for measuring large values of resistance in
insulation testing applications.
AEMC Instruments manufactures electrical testing and measurement
instruments, including clamp meters, power quality analyzers,
ground resistance testers, and data loggers. The company, founded
in 1893, is headquartered in Foxborough, MA.
