Manufacturer: Megger Brand: Megger Model: 247000

The Megger 247000 series digital low-resistance ohmmeter measures resistance in switch and circuit breaker contacts, transformers, generators, motor windings, metal alloys, graphite electrodes and other low-resistance electrical wiring. The meter is autoranging and digital for safety and ease of use. Kelvin-type four-wire measurement of resistance eliminates errors caused by the lead and contact resistances of the meter. Measurements taken by the ohmmeter are accurate to + or – 0.25%. The digital readout has an automatic zero circuit to eliminate field test inaccuracies. The 247000 series is used by electricians and electrical contractors.Electrical test meters report electrical circuit properties, such as voltage, resistance, capacitance, and continuity. 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 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. Meters measure electrical properties and are safety rated to measure a specific range of results. The range on the meter should be higher than the maximum anticipated value to be measured. An electrical test meter has multiple settings corresponding to potential ranges of values for the properties it can measure. A manual ranging meter requires the operator to flip through different settings until the correct range is reached. An autoranging meter cycles through range settings automatically until it reaches the correct range. Megger manufactures equipment for cable fault lo...

Manufacturer: Kyoritsu Brand: Kyoritsu Model: 3132A

The Kyoritsu analog megohmmeter is an insulation tester with three test voltages—250, 500, and 1,000V—for measuring insulation resistance to 400MΩ to indicate the condition of windings or cables in motors, switchgears, electrical installations, and other insulated equipment, and it also measures low-resistance continuity and lights an indicator and sounds a buzzer when a live circuit is detected. When measurement is complete and the test button is released, residual voltage is automatically discharged from the circuit under test. The test button can be locked for extended measurement sessions. The meter is available in a model (B009TALC6S) that measures low-resistance continuity to 20Ω and has a backlight for visibility in low light, and in a model (B009TALDUI) that measures low-resistance continuity to 500Ω and detects AC voltage to 600V. The unit has a battery voltage check that indicates the condition of the batteries. It is rated for category (CAT) III installations to 300V, which covers equipment in fixed installations, such as switches in the fixed installation and some industrial equipment that is permanently connected to the fixed installation. It comes with a set of test leads, a test lead storage pouch, two 500mA/600V fuses, a shoulder strap, six 1.5V AA batteries, and instructions.

Manufacturer: Megger Brand: Megger Model: 241005-7

The Megger 241005-7 series duplex test lead with gold-plated Kelvin clip is for use with Megger DLRO10HD, DLRO10, DLRO10X, 247000, 247001, 247002, 247100, 247101, and BT51 digital low-resistance ohmmeters. This 7' (2 m) long duplex test lead measure both current and resistance when taking four-wire resistance measurements, which are more accurate than two-wire resistance measurements and allow low resistance values to be detected. The lead has a maximum test current input of 10 amp. The gold-plated Kelvin clip provides low contact resistance and has better resistance to corrosion and wear than a silver plated clip. The Kelvin clip directs current through one jaw and potential through other jaw when taking resistance measurements on cables and small wires. It has a jaw opening of 0.5" (1.3 cm).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, telecommu...
