Autoset
When you push the Autoset button once, the oscilloscope identifies the type of
waveform and adjusts controls to produce a usable display of the input signal.
When you press the button for more than 1.5 seconds, it will perform the
Autorange function. It will displays the Autorange Menu and activate or
deactivate the autoranging function.

Volts/Div Adjusted
The Autoset function examines all channels for signals and displays
corresponding waveforms. Autoset also determines the trigger source based on
the following conditions:
■
If multiple channels have signals, the oscilloscope displays the channel with
the lowest frequency signal.
■
If no signals are found, then the oscilloscope displays the lowest-numbered
channel when Autoset was invoked.
■
If no signals are found and no channels are displayed, then the oscilloscope
displays and uses channel 1.
