Before you select a power meter and its associated sensors, make sure that you have taken the following four steps, each of which can influence the accuracy, economy, and technical match to your application.
- Understand the characteristics of your signal under test and how they interact with the power sensing processes
- Understand power measurement uncertainties, and traceability to a primary power standard at a national laboratory, such as the U.S. National Institute of Standards and Technology(NIST)
- Understand the characteristics and performance of available sensor technologies and operating features of various power meters
- Make the performance comparison and select the right product for your application
