Designing an instrumentation system for high current measurement requires careful consideration of the trade-offs associated with each type of sensing device. The purpose of this application note is to help engineers understand the sensing choices available and the corresponding trade-offs with each technology.


In a research published in the SAE International Journal of Fuels and Lubricants, researchers from Georgia Southern University use a Yokogawa Test&Measurement DL850 ScopeCorder to record and monitor data from a piezoelectric pressure transducer in-cylinder, a pressure sensor for intake pressure, and an optical rotary encoder for engine rotational position and speed, and to test the combustion and emissions characteristics on an experimental engine.


In this research paper published by the Department of Mechanical Engineering at Georgia Southern University, researchers use a Yokogawa Test&Measurement DL850 ScopeCorder for real-time high-speed data acquisition on a research engine to investigate the low-temperature combustion regions of aerospace F24 and ULSD for emission reduction.


We developed an algorithm to optimize induction motor operation and produce an average power consumption savings of at least 10%. To demonstrate our algorithm’s effectiveness, we needed a proven and verified system that would give these results credibility. The solution provided by Yokogawa Test&Measurement enabled us to monitor and refine our algorithm using real-time speed, power, and temperature readings – data that would normally be incredibly difficult to accurately obtain. Having these real-world results that demonstrate the effectiveness of our algorithm means we can be more efficient with our own customers. —Neil Singer, President, AC Kinetics


It’s not an exaggeration to say I owe a good bit of my career success to Yokogawa Test&Measurement. By using their ScopeCorders that combine the best parts of an oscilloscope and DAQ, projects that once took weeks across multiple instruments suddenly only took a few hours with just one instrument. The impact on what I could accomplish really was quite remarkable, and my ability to accurately complete projects in record time made me look incredible. No matter how complex or convoluted the task, the ScopeCorders never fail to easily handle anything I throw at them. They’re amazing instruments and I tell others about them every chance I get. —Kenneth Shoemaker, Automotive Industry Consultant/Owner at Panama Prototypes


I’ve been using Yokogawa Test&Measurement instruments for power measurement and analysis for several years and they always get the job done. They provide extensive and thorough documentation for their equipment and their drivers are very handy. Features like screengrabs of test results for easier sharing and the remote interface (which minimizes the time we spend having to automate tests) have proven to be incredibly helpful. My team needs instruments that are well documented, easy to use, and reliable. Yokogawa instruments check all these boxes.

For standby power measurement and energy certification maintenance, we rely on Yokogawa Test&Measurement instruments. Their precision, accuracy, and ease-of-use are unrivaled. When given a choice between other test and measurement equipment and Yokogawa, our technicians always go for Yokogawa first. The support team provides thoughtful insights based not just on our industry but also our company’s specific needs. My team has used Yokogawa Test&Measurement instruments for decades and will continue to do so well into the future.

—Director of Technology Laboratories, International Multi-Brand Manufacturer of Major Home Appliances


When I started with my company almost 20 years ago, Yokogawa Test&Measurement instruments were already in use and the engineers had no intention of switching. In fact, we still routinely use some of the older instruments because, well, they just work! The equipment doesn't really become obsolete, and they support their instruments as long as is feasible, which ultimately saves us money. Even so, as things change in our industry Yokogawa adjusts to meet those changes. From our sales representative through technical support and more, I can count on the Yokogawa team to really listen and work with us to provide a specific solution for unique problems.

    Why should you be concerned with your product’s power system voltage and current harmonics? From an engineering perspective, harmonics produce excessive heat in equipment that causes significant damage and results in inefficient operation. From a business perspective, compliance is an absolute requirement for entry into global markets. To minimize or eliminate these issues and establish acceptable levels of harmonics, numerous power quality standards with specifications and limits for harmonic distortion, such as IEEE 519-2014 and IEC61000-3-2, have been introduced. During this webinar, attendees will gain knowledge on the inner workings of harmonics, learn best practices for accurately measuring harmonics, learn to recognize and distinguish the critical difference between DFT and FFT, and discover important measurement tradeoffs across various test equipment.
