Truevolt Series 6½- and 7½-Digit Bench Digital Multimeters   Measure with unquestioned Truevolt confidence   What truevolt technology means to you:   Measure with unquestioned Truevolt confidence Truevolt technology starts with an analog-to-digital converter that enables a patented metrology-grade architecture. Using this architecture, Keysight delivers a good balance of measurement resolution, linearity, accuracy, and speed at a value price, all derived and guaranteed per ISO / IEC 17025 industry standards.   Worry about the quality of your design, not the quality of your measurements Noise and injected current: Keysight Truevolt digital multimeters (DMMs) contribute less than 30% of the injected current as alternatives. Compared with some lower-cost alternatives, Truevolt DMMs offer almost 100% less noise.   Input bias current Ideally, no current flows into the measurement terminals of your DMM. In real measurement situations, input currents create additional measurement errors. Truevolt DMMs take care of input bias current. Some alternative DMMs offer 20% or more, poorer performance (some are too noisy to measure).   Digital AC root-mean-square (RMS) measurements For meters in this class, only Keysight uses digital direct sampling to make AC RMS measurements. The result is a true RMS calculation technique that avoids the slower response of analog RMS converters used in all other vendors’ 6½-digit DMMs. This technique allows for crest factors up to 10 without additional error terms. This is a unique, patented technique — used only by Keysight.   Control, automate, and simplify  with PathWave BenchVue software Keysight PathWave BenchVue software for the PC eliminates many issues surrounding bench testing. By making it simple to connect, control instruments, and automate test sequences, you can move past the test development phase and access results faster than ever before. The DMM app in BenchVue enables control of DMMs to visualize measurements, perform data logging, and annotate captured data. Easily control your DMM to quickly build automated tests, log measurements, and save precious time.

選購桌上型數位萬用電錶的注意事項

The digital multimeter (DMM) is the most commonly used instrument on an engineer’s bench. We use it almost every day. Whether we are making a quick and simple voltage measurement or data logging temperature over a long period of time, our DMM just has to work. It is the workhorse of the engineering bench. In many ways, most of us are in a one-sided relationship with our DMMs. In exchange for all the work that it does, we expect very little maintenance and upkeep from our end in return. Even though the DMM is such an important instrument, we do not spend nearly enough time thinking about it. From concept to prototype turn-on and debugging all the way through testing and validation, the DMM is ever-present through the entire product cycle from beginning to end. This eBook will take a closer look at the DMM and all that it does. We will explore 10 things that you should know about DMMs. The topics covered are applicable whether you are considering your next DMM purchase or you want to get more from the DMM currently on your bench.
