The Polar co-ordinate function enables the operator to convert the displayed data from the conventional
Cartesian co-ordinates (X,Y,Z) to Polar (Length + Angle) co-ordinates for any plane XY, XZ or YZ.
Pressing the switches between the two displays.
The can be selected from the Absolute, Incremental or Sub Datum modes.

EXAMPLE:
The keystrokes for entering the following Line Holes are
shown. X and Y axes are assumed at Absolute Zero.
NOTE: Length is the total length of the line hole
sequence, not the distance between adjacent
holes.
