Scale adjusts the range of velocities that are displayed. Upward
presses increase scale and downward presses decrease it. It is
available in Velocity, PDI, and DPDI. It is not available in
Freeze/Cine.
Normally, signals above the baseline are positive velocities (moving
toward the transducer). However, when Invert is pressed then
negative velocities are above the baseline. Invert does not affect the
baseline position. Invert is not available in PDI mode.
The Baseline control adjusts the Color baseline. Upward presses
move the baseline up on the scale and downward presses move the
baseline down. Baseline is not available in PDI mode.
The Filter control removes excessive noise from movement of
vessel walls. Options of Low, Med and High are available.
