Auto Scale (PvT)
Selects the setting mode for the horizontal scale of the PvT view. Note that this menu
is only valid in PvT measurement mode.
Remarks:
⚫ When you select "Auto", the auto scale function enables you to automatically set
the reference time and the X-axis scale based on the acquisition time and
reference position.
— The X-axis scale is 10% of the acquisition time.
— The reference time is set to a different value according to a different
reference position. When the reference position is set to "Left", the
reference time is 0 μs; when set to "Center", the reference time is half of
the acquisition time; when set to "Right", the reference time equals to the
acquisition time.
⚫ When you set the reference time and the X-axis scale manually, the auto scale
function will automatically switch to "Manual".
