Autoscale function
This is a very useful function for first-time users who want to perform a simple and quick check of the input
signal. This function is used to automatically track signals even if the signals change at any time. Using the
Autoscale function, the instrument can automatically set up the trigger mode, voltage division and time scale
according to the type, amplitude and frequency of the signals.
