ABSTRACT
Data logging and recording is a very common measurement application. In its most basic form, data logging is the measurement and recording of physical or electrical parameters over a period of time. These parameters can be temperature, strain, displacement, .ow, pressure, voltage, current, resistance, power, or any of a wide range of other measurement types. Real-world data-logging applications are typically more involved than just acquiring and recording signals, as illustrated in Figure 35.1. They usually involve some combination of online analysis, offline analysis, display, report generation, and data sharing. In addition, many data-logging applications are beginning to require the acquisition and storage of other types of data. One example would be recording sound and video in conjunction with the other parameters measured during an automobile crash test.
