If you one day find yourself with a transformer that might or might not have a shorted winding, your first inclination for verifying your suspicions might be to find an inductance meter. The problem with powering up an inductance meter for this situation is that the inductance of a transformer containing a shorted turn might […]

MTI Instruments wins coveted Leap award
MTI Instruments, Albany, N.Y., has won a siliver medal in the 2022 Leap Awards competition. The LEAP Awards celebrates the most innovative and forward-thinking products serving the design engineering space. MTI won in the test and measurement category, for test and measurement equipment as typically used by design and development engineers engaged in product design […]
How to screw up a capacitance measurement
Consider the task of performing a capacitance test using an LCR meter or a good multimeter such as the Fluke 287 True RMS Multimeter. If the capacitor under test is an electrolytic or film-based device, the main measurement concern is often just ensuring the capacitor is not under power or doesn’t have a stored charge–electrolytics […]
Things to know about multimeters
For years, ohmmeters have been integrated into the electrician’s multimeter. This is convenient, because ohms and volt are the most-performed measurements. Also, only a single instrument must be purchased and maintained. Multimeters are further subdivided into ac, bench-type multimeters and hand-held, battery-powered multimeters. The hand-held instruments are more convenient. Most often just grab your handheld […]
Intrinsically safe meters simplify mechanical, electrical bond testing
The TEGAM 700 series of bond meters now include two handheld measurement tools. The TEGAM 720A and TEGAM 730A bond meters are suitable for use in the manufacture and maintenance of automotive, aerospace, renewable energy equipment and other applications in which testing of the integrity of mechanical and electrical bonds is a critical requirement. The […]
Power choke testers measure up To 4 kA/7.7 kJ
The ed-k DPG Power Choke Tester family is a unique series of innovative measurement instruments for inductive power components, using currents up to 4 kA and pulse energy up to 7.7 kJ. The DPG series uses a large-signal impulse measuring method to provide a complete inductance curve as a function of the current L(i), or […]
YouTube videos shed light on frequency and wavelength
Today, an advanced multimeter such as the Fluke 287 in volts mode accurately displays frequency. High frequencies are displayed in a bench-type frequency counter, which can read above 100 GHz. At still higher frequencies, measurements are made indirectly via heterodyning to down-convert the signal. Using a diode or similar device as a mixer, a frequency […]
Key considerations for RF power measurement equipment
The choice of power sensor and meter greatly depends on the qualities of the signal being measured. Bob Buxton, Boonton Electronics Today’s complex modulation schemes and pulsed communication modes have brought the need to measure RF power ever more accurately and efficiently. There are multiple technologies available for the measurement of RF power, falling into […]
3U development platform handles SOSA 1.0 and CMOSS designs
A 12-slot, 3U Development Platform is aligned to SOSA 1.0 and CMOSS and features high-speed RF and optical I/O connectivity on a number of key SOSA profiles while supporting both I/O-intensive and compute-intensive processor slots, two switch slots and one PNT slot as part of the test solution. Prior to its official release, the development […]
Measuring and using static electricity
Many moons ago, a future member of our editorial staff was playing with his very first multimeter. He was a farm kid. One of his first experiments was to put the negative lead of the meter on a ground rod and the positive lead on one of the metal bands used to reinforce the interlocking […]
