A data logger (or transient recorder) is a direct registering instrument to display signal voltages, plotted against time (Yt) or against another signal voltage (XY). The data logger will measure in a continuous streaming mode, until it is stopped by the user. While measuring, samples will be transferred directly to the computer where they are processed and displayed and when required stored to disk. Any change in the input signal(s) will be immediately visible.
All TiePie engineering measuring instruments can be used as a data logger. Read more.
