An electrical conductor warms up when it conveys current. If the heat is high enough the conductor can be damaged, so it is beneficial to limit current flow. Three-phase electrical distribution systems are highly effective in limiting current flow without reducing the amount of power delivered to the load. They do this by separating phases […]

Cabling Certification System now supports Legrand Clarity, Superior Essex PowerWise PoE products
The Fluke Networks Versiv Cabling Certification System now supports Legrand’s family of Clarity cords and high-density jacks and Superior Essex Communications’ LP PowerWise cabling products. The combined PowerWise and Clarity system is designed to provide superior performance for power over Ethernet (PoE), including the IEEE 802.3bt draft 3.0 standard. This new capability extends Fluke Networks […]
Handy test equipment for troubleshooting
Not all test equipment needs to be expensive. Here are a few helpful tools that won’t break the bank. Electricians doing residential, commercial or industrial work need to know with absolute certainty whether a wire or terminal is live and whether a given piece of electrical equipment is energized at the power input terminals. Usually, […]
Analyzer gauges Power Quality and Electric Motor characteristics
Fluke and Veros Systems have entered into an agreement to collaborate on asset performance and condition monitoring technologies, with the goal of increasing visibility into the efficiency and reliability of electric motor driven machines. The Fluke 438-II Power Quality and Motor Analyzer is the first tool to result from that collaboration. Fluke is the leading provider of power […]
VIDEO: Using a Fluke Bench-Type Multimeter to Measure DC Output from a Tektronix Programmable Power supply
We connect a Fluke 8808A bench-type multimeter to a Tektronix PWS4305 DC power supply and test both instruments for accuracy. Hello once more and welcome to our 58th Test and Measurement Video. This is Part 2 of a discussion begun in Video 57 in which we demonstrated some interesting aspects of the amazing Fluke 8808A […]
Fluke 8808A bench-type multimeter
The multimeter had its roots in a surprising observation by Hans Christian Ørsted during a lecture in 1820. He saw that a compass needle deflected from its alignment with the earth’s magnetic north pole when a metal conductor carrying electric current was moved close by. This action suggested that an analog meter could be built […]
VIDEO: Fluke 8808A Bench-Type Multimeter, Part One
Part One of a demonstration of principle functions and features of the Fluke 8808 bench-type multimeter. Hi and welcome to our 57th Test and Measurement Video. Right now we’ll look at the amazing Fluke 8808A bench-type multimeter. For perspective, here are some far less sophisticated but sometimes useful tools that will measure electrical energy. This […]
Infrared camera sports on-screen editing capability
Fluke Corp. introduces the new Fluke TiX620 Infrared Camera, joining the TiX640, TiX660 and TiX1000 models as part of the Fluke Expert Series. The TiX620 is an ideal infrared camera for the experienced thermographer. Its 640 x 480 resolution provides high measurement accuracy and 5.6 inch high-resolution LCD screen affords a premium in-field viewing experience […]
When scopes measure voltages not referenced to ground
Consider a typical bench-type oscilloscope that connects to the ac outlet. It typically has an equipment grounding conductor that connects to the building’s electrical grounding system. Consequently, it is hazardous to connect the scope probe’s ground return lead to a printed circuit board or electrical equipment terminal or wire that is referenced to and floats […]
DMM paired with thermal imager to handle troubleshooting tasks
Thermal imagers are invaluable to help quickly troubleshoot electrical equipment, panels, and transformers but electricians and maintenance technicians often don’t have access to one when they need it. Fluke announces the 279 FC TRMS Thermal Multimeter, the first test tool to integrate a full-featured true RMS (TRMS) digital multimeter (DMM) with a thermal camera in […]
