Megger 6111-503 2-Piece Duplex Handspike Set for Use With DLRO10 and DLRO10X Digital Microhmmeter, 4' Length

Model: 6111-503   |    Mpn: 6111-503   |    PartNumber: 6111-503   |   Asin: B005T9CZ3W

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. 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 company, founded in 1889, is headquartered in Dover, England, and meets International Organization for Standardization (ISO) 9001:2008 standards.

Instek GOM-801H Four-Input Digital Milliohm Meter, 7 Test Ranges, 20 Kilohms Resistance

Model: GOM-801H   |    Mpn: GOM-801H   |    Ean: 4719692504579   |    PartNumber: GOM-801H   |   Asin: B005DTHP88

The Instek GOM-801H digital milliohm meter is a four-input, manual-ranging meter with seven test current/resistance ranges for precise, low-resistance measurements from 10 microohms ( ) to 20 kilohms (k ) of switches, relays, test wires, cables, printed circuit boards, and other electrical components. Four input terminals enable Kelvin-type, four-wire resistance measurements, which are more accurate than two-wire resistance measurements. The meter's comparator function allows the user to enter settings for high and low thresholds, lights a high or low indicator when readings fall outside the settings, and triggers a buzzer and lights a go indicator when readings are within the settings. The meter has a 3-1/2-digit LED display and a power cord for connecting to 100/120/220/230V AC power. It comes with a set of test leads with Kelvin clips and instructions. Milliohm meters are commonly used for electrical maintenance and testing in industries such as heating, ventilation, and air conditioning (HVAC), transportation, telecommunications, power plants, and utilities, among others.

This manual-ranging meter allows the user to select the operating range for measurements. Accuracy and resolution specifications vary according to the range being measured. It meets European Standard (EN) and International Electrotechnical Commission (IEC) safety standard 61010-1 and has European Conformity (CE) marking.

Specifications Resistance measured 10 to 20k Test current/resistance ranges 20m /1A, 200m /1A; 2 /0.1A, 20 /10mA; 200 /1mA, 2k /100 A, 20k /10 A Standards met European Standard (EN) and International Electrotechnical Commission (IEC) safety standard 61010-1; European Conformity (CE) marking Power supply Power cord for 100/120/220/230V AC power Weight 2kg Dimensions (H x W x D) 95 x 280 x 230mm H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Ohmmeters 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. Microohm meters and milliohm meters measure small resistance values, and megohm meters (also known as megaohm meters, or insulation resistance meters) measure large resistance values. Ohmmeters have an internal power supply, such as a battery or a capacitor, which supplies current to a circuit or component that is turned off. Test leads are connected in a series to the meter and the circuit or device being tested. As current flows through the circuit or device, the meter calculates the difference in voltage between the leads and measures the resistance. Ohmmeters have either two or four input terminals for test lead attachment. The two-terminal, or two-wire, measurement method provides measurements that include the resistance of the circuit or device being tested and the resistance of the test leads. Megohm meters generally use the two-wire method because it provides sufficient accuracy for measuring large values of resistance in insulation testing applications. The four-wire method eliminates resistance from the test leads and measures only the resistance of the circuit or device being tested. Milliohm and microohm meters generally use the four-wire method because it provides a greater degree of accuracy for measuring smaller values of resistance in low-resistance applications. GW Instek manufactures test and measurement equipment such as oscilloscopes, spectrum analyzers, signal testers, and video surveillance systems. The company, founded in 1975, is headquartered in Taipei, Taiwan.

Extech 380580 Battery Powered Milliohm Meter

Model: 380580   |    Mpn: 380580   |    Ean: 0793950385814   |    PartNumber: 380580   |   Asin: B000NI69EA

Battery Powered Milliohm Meter Battery operated to facilitate in-the-field use, Extech's 380580 Milliohm Meter provides five resistance ranges with resolution as low as 0.1 milliohms, and the 4-wire Kelvin clip connection provides optimum accuracy. Typical applications include transformer, motor coil, and PC board resistance measurements.

Additional Features Measurements are displayed on a large, 2000 count LCD. Additional features include over-temperature and over-voltage protection, Auto-Hold, Auto power off, and invalid test indicators to prevent inaccurate measurement.

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 ( ) are Milli- (m ) and Micro-( )Ohms. One MilliOhm (1m ) is equal to one thousandth of an ohm (0.001). One MicroOhm (1 ) is equal to one millionth of an ohm (0.000001). For example, 0.5 ohms (one half an ohm) is equal to 500m .

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.

AEMC 1050 Digital Megohmmeter, 50/100/250/500/1,000V Test Voltages, 4,000 Gigohms Insulation Resistance, 400 Kilohms Low-Resistance, 5 Microfarads Capacitance, 1,000V Voltage

Model: 1050   |    Mpn: 2130.01   |    Ean: 0685338150148   |    PartNumber: 2130.01   |   Asin: B008S0AVGW

The AEMC 1050 digital megohmmeter is an auto-ranging insulation tester with a voltage safety check and five test voltages 50, 100, 250, 500, and 1,000V for measuring insulation resistance to 4,000G to indicate the condition of windings or cables in motors, switchgears, electrical installations, and other insulated equipment, and it also measures low-resistance to 400k , capacitance to 5 F, and AC and DC voltage to 1,000V, disabling insulation testing when a voltage greater than 25V is detected. The R-DAR-PI (resistance-dielectric absorption rate-polarization index) function calculates and displays the DAR and the PI, which are measurements over time that give a truer indication of insulation condition than single-point measurements. The timer function allows timed testing from 1 to 59 minutes. High and low thresholds for insulation and resistance measurements can be set, triggering an alarm when readings fall outside the settings, and will be retained even after the meter is powered off. When measurement is complete, the meter enters voltage detection mode and automatically discharges residual voltage from the circuit under test. A memory function allows storage and recall of 20 readings. The meter can perform a continuity check up to 40 and buzzes to confirm that a circuit conducts electricity. Built into a double-insulated, dual-walled field case, the meter has a 4,000-count LCD with a backlight for visibility in low light. The display shows readings numerically and on a 31-segment bar graph. Megohmmeters are commonly used for electrical maintenance and testing in industries such as HVAC, transportation, manufacturing, mining, and utilities, among others.

This auto-ranging meter automatically selects the appropriate operating range for measurements. It is rated for category (CAT) III installations up to 600V, which covers energy-consuming equipment connected to a fixed installation, including household, office, and laboratory appliances. The unit automatically turns off after five 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 set of test leads, a set of alligator clips, a test probe, eight 1.5V C batteries, fuses, a detachable accessory pouch, and instructions. For remote operation, the meter has an input for connecting an AEMC 2118.97 remote test probe (sold separately).

. 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.
