Autorange
When you hold the Autoset button for more than 1.5 seconds, the oscilloscope
activates or deactivates the Autorange function.
This function automatically adjusts setup values to track a signal. If the signal
changes, the setup continues to track the signal. When you power on the
oscilloscope, autoranging is always inactive.

The following conditions cause autorange to adjust settings:
■
Too many or too few waveform periods for a clear display of the trigger
source (except when in Vertical Only)
■
Waveform amplitude too large or too small (except when in Horizontal Only)
■
Ideal trigger level changes
When you push the Autoset button for more than 1.5 seconds, the oscilloscope
enters the autorange mode and adjusts controls to produce a usable display of the
input signal.
