The Autorange function is usually more useful than Autoset in the following
situations:
Analyzing a dynamically changing signal
Quickly comparing a sequence of several signals without adjusting the
oscilloscope. This is very useful if you need to use two probes at the same
time, or if you need to use a probe in one hand and are holding something
else in the other.
Controlling which settings the oscilloscope automatically adjusts
If your signals vary in frequency, but have similar amplitudes, you can use
Horizontal Only autoranging. The oscilloscope will adjust the horizontal settings,
but leave the vertical settings unchanged. This way, you can visually estimate
the amplitude of the signal without worrying about the vertical scale changing.
Vertical Only autoranging works similarly, adjusting vertical parameters and
leaving the horizontal settings unchanged.
When you push the AutoSet button, the oscilloscope identifies the type of
waveform and adjusts controls to produce a usable display of the input signal.
