Auto Scaling
Toggles Auto Scaling between On and Off.
When Auto Scaling is On, pressing the Restart front-panel key results in
automatically determining scale per division and reference values based on the
measurement results.
When you set a value to either Scale/Div or Ref Value manually, Auto Scaling
automatically changes to Off.
