The Hioki 3453 digital insulation tester is an auto-ranging megohmmeter with four test voltages—125, 250, 500, and 1,000V—for measuring insulation resistance to 4,000MΩ to indicate the condition of windings or cables in motors, switchgears, electrical installations, and other insulated equipment, and it also measures low-resistance to 200Ω and AC voltage to 600V, lighting a warning indicator when voltage greater than 40V is detected. The comparator function allows a reference value to be set, identifies subsequent readings as high or low in comparison, and triggers a buzzer when readings fall below the reference value. The memory function stores up to 20 readings. To aid documentation of readings, the data hold function keeps the most recent reading on the display. When measurement is complete, the discharge function clears residual voltage from the circuit under test. A continuity buzzer confirms that a circuit conducts electricity. The meter has a 4,000-count LCD with a backlight for visibility in low light that automatically turns off after eight seconds. The LCD shows the reading numerically and in a 42-segment bar graph. This auto-ranging meter automatically selects the appropriate operating range for measurements. It is rated for category (CAT) III installations to 600V, 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. The unit automatically turns off after 10 minutes of non-use to conserve battery life and has a low-battery indicator that signals when the batteries need to be replaced. It comes with a test probe, a detachable cover to protect the display, four 1.5V AA batteries, and instructions. It is available with or without a carrying case. Megohmmeters are commonly used for electrical maintenance and testing in industries such as HVAC, transportation, manufacturing, mining, and utilities, among others.SpecificationsMaximum insulation resistance measured4,0...

View larger 220V High Resolution Precision Milliohm Meter Compact and precise, the Extech 380560 Milliohm Meter has 7 ranges and measures down to 0.1 milliohms using 4-wire Kelvin clip test leads. Measurements are displayed on the unit's large 0.8-inch, 1999-count LCD. Other Features Automatic zero, 5V test voltage, and a built-in comparator for Hi/Lo/Go resistance testing or selection. Operates on 220 VAC and comes complete with 4-wire cables with Kelvin clip connectors. 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 bother measuring resistances so low? It may seem like too small a resistance to be of any consequence but many safety standards (UL, CSA, VDE, etc.) require that such resistances be measured during the manufacture of consumer products, hand tools, and many appliances. A good example is the testing of kitchen appliances. 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.

Manufacturer: Megger Brand: Megger Model: 242006-18

The Megger 242006 series duplex test lead with Kelvin clip is for use with Megger DLRO10HD, DLRO10, DLRO10X, 247000, 247001, 247002, 247100, 247101, and BT51 digital low-resistance ohmmeters. This 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 Kelvin clip directs current through one jaw and potential through other jaw when taking resistance measurements on cables and small wires. It has a 1.5" (4 cm) jaw opening.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.

The Megger 6111 series two-piece duplex test lead set with spring-loaded duplex hand spikes is for use with Megger DLRO10HD, DLRO10, DLRO10X, and BT51 digital microhmmeters. These duplex test leads 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 spring-loaded hand spikes compress to make contact with a conductor. Light-emitting diodes (LEDs) on one probe confirm connection and the presence of live current when used with the Megger DLRO10 microhmmeter, and can indicate test pass/fail when used with the Megger DLRO10X microhmmeter. There is 0.23" (6 mm) between the current and potential probe tips on the duplex hand spikes.A test probe, test lead, test prod, or scope probe transmits an electrical signal to a testing device for display and analysis.
