Scan Mode Display. You can use the Horizontal Scan acquisition mode (also
called Roll mode) to continuously monitor signals that change slowly. The

to the user manual for the application.
Autorange
WhenyoupushtheAutoRange button, the oscilloscope activates or deactivates
the Autorange function. An LED light turns on adjacent to the AutoRange button
that indicates when the function is active.
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.
