EU Settings
All waveform data is initially scaled, annotated, and displayed in volts, which in many cases is not very meaningful. Change EU (Engineering Units) Settings to give meaning to the displayed data. Instead of volts, your data can be scaled, annotated, and displayed in significant engineering units (i.e., PSI, RPM, lbs, ft/s, etc.). Calibration is done primarily for display purposes, it makes the data more visually appealing and easier to understand on your monitor. However when you calibrate, the calibration information is saved in an accompanying header file along with the data file. This header file stores the calibration information, allowing it to be re-used and thus eliminating the need to calibrate again. So, calibration is not entirely for display purposes.
