Data Acquisition. The collection and storage of data on a Vehicle, also termed“ data logging”. Data loggers acquire and store data until the data is downloaded.
For Kart applications, data loggers are acceptable, provided there is no electrical connection between the data logger and the ignition system of the Kart other than to an insulated section of the high-tension( HT) lead. Any lap-timing device used as part of the data logger must adhere to the lap-timing section of these definitions.
In Karting terms, a data logger is a combination of an electronic memory and a Series of sensors and looms, usually allied to a beacon detector for lap-timing. Data is usually viewable on a software program on a computer after download from the memory. A data logger may have Driver instrumentation connected to it for on track display of information to the Driver.
