What's in the Box Unit is housed in a built-in water resistant case and comes with eight AA batteries, two sets of test leads (4-wire with four alligator clips and 4-wire with two Kelvin alligator clips), and user manual. What is a MilliOhm? The units of measure for resistances less than 1 Ohm (Ω) are Milli- (mΩ) and Micro-(μΩ)Ohms. One MilliOhm (1mΩ) is equal to one thousandth of an ohm (0.001). One MicroOhm (1μΩ) is equal to one millionth of an ohm (0.000001). For example, 0.5 ohms (one half an ohm) is equal to 500mΩ. Why are 4-wire connections required when making milliohm measurements? Test leads always introduce a small amount of additional resistance into a measurement. This is acceptable in non-critical measurements such as megohm resistances. However, when measuring milliohms in a critical application, any additional resistance can render the measurement useless. This is why 4-wire (Kelvin) connections are imperative.

Available in handheld or benchtop form, they detect electrical problems in equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Single-function meters, such as battery testers and voltage testers, measure one property of a circuit, and multimeters measure multiple properties. Electrical test meters display information either in analog form using a needle that moves on a calibrated scale, or in digital form using digits or a graphic representation on an LED screen. Meters have electrical properties that are to be measured and the anticipated range of results, and should have a rating that is higher than the maximum value of the anticipated range. An electrical test meter has...

Manufacturer: AEMC Brand: AEMC Model: 6501

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-cr...

Manufacturer: Megger Brand: Megger Model: 242104-2-26

The Megger 242104-2 series duplex test lead with C-clamp is for use with Megger 247100, 247101, DLRO200, and DLRO600 digital low-resistance ohmmeters. This duplex test lead measures both current and resistance when taking four-wire resistance measurements. The lead has a maximum test current input of 100 amp. The C-clamp provides a hands-free connection to a conductor and can accommodate conductors up to 4" (10 cm). The C-clamp directs the current through the clamp and screw and the potential through a four-point anvil that is insulated from the clamp.A test probe, test lead, test prod, or scope probe transmits an electrical signal to a testing device for display and analysis. Designs range from simple test leads with probe-style or clamp-on tips to more complex oscilloscope probes and current detectors. Some test probes, such as basic test leads, have wires with tips for connecting to test equipment. Other test probes, such as voltage detectors, are built into the meter. Depending on what is to be tested, the probe might either be passive or have active parts that require external power to operate. Some probes require contact for testing, while some are capable of taking measurements from a distance. Some also have finger barriers, insulation, or other features to help protect the operator's hand from electrical shock and burns. Test probes are rated according to the amount of voltage, current, temperature, or other input they can measure. When choosing a test probe, the maximum amount of input that the probe can measure should match or exceed both the maximum amount that can be tested by the test equipment, as well as that of the property expected to be present in the application.Megger manufactures equipment for cable fault locating, protective relay testing, telecommunications and data integrity, and power quality testing under multiple brand names, among them Megger, Biddle, States, and AVO.
