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.SpecificationsMaximum insulation resistance measured200MΩTest voltage500VMaximum low-resistance measured500kΩMaximum AC and DC voltage measured600VInstallation ratingCAT III, 300V; CAT II, 600VStandards metEN safety standard 61010-1; CE markingPowerHand-cranked generatorWeight1.1kg/2.5 lbs.Dimensions (H x W x D)*120 x 120 x 130mm/4.7 x 4.7 x 5.1 inches*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.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. What's in the Box?AEMC 6501 analog megohmmeterSet of test leadsSet of alligator clipsTest probeSoft carrying caseInstructions
