This method is used when applying the same amplitude range condition to all data. Amplitude means the height of signal waveform. In general, maximum and minimum values of amplitudes vary depending on measuring conditions. Rescaling by Extreme is the very process of changing different ranges of amplitude to the specified range. Select data you want to apply this method in Analysis Window and click the icon of Rescaling by Extreme in Analysis Tool Bar. This will display a dialogue box for amplitude setting to set the range of amplitude as shown in the following figure. Input maximum and minimum values of amplitude as you need and click Apply button. Example shown in the following figures shows the amplitude with scale of 1 to -1. As you can see, different ranges of amplitudes by channels are adjusted to be within 1 to -1. The graph is shown in Display Window and registered at Analysis Window.
