If you are able to install your own TV dish satellite system and a wireless home network for PCs,you have a head start on installing and maintaining electronic field measurement equipment. Today’s measurement technicians and engineers are required to operate and maintain a variety of Hi-Tech Field measurement equipment. Most of the Held instrumentation is tightly integrated in a complete system functional environment. The larger the metering station, the more complex the system. The goal of this paper is to provide an introduction to electronics based on current field measurement technology.
