Uses the *MEASUREDISPG subroutine of the Unit Macro processing unit to draw an arc of the measured

radius whose starting angle is -90

circular scan edge position processing unit (Processing Unit number 5). The displayed arc is a wide arc

whose outer radius is the measured maximum radius and whose inner radius is the measured minimum

radius. The measured X/Y coordinates and radius, and maximum/minimum radii can be gotten with External

Reference Data numbers 5, 6, 7, 8, and 9 respectively.

To display the arc at the fixed position regardless of the position compensation result, specify the assigned

processing unit number to this Unit Macro processing unit (where the *MEASUREDISPG subroutine is used)

for the <unitNo> parameter.
