Couplings When this parameter is set to On, pressing the front-panel Restart key activates the scale coupling
function, that automatically determines 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 is
automatically set to Off
