Display Resolution
The display resolution will normally be the
same as the encoder resolution. However, if the
job tolerance is coarser than the encoder
resolution (for example, the job tolerance may
be ±0.005"), you can adjust the display
resolution so you won’t be tempted to waste
time by machining to a finer resolution.
Use the
COARSER
and
FINER
softkeys to cycle
through all the possible choices. The choices
available depend upon the resolutions of the
scales.
Scale Factor
The scale factor can be set to scale the workpiece up or down from the preset
or programmed size. All preset and displayed dimensions are multiplied by
this scale factor. All programmed dimensions will be multiplied by this scale
factor when the program is run. The numbers
in your program are not changed.
A scale factor of 1.000 causes the readout to
use preset or programmed dimensions exactly.
Values greater than 1 cause parts to be made
larger; values less than 1 cause parts to be
made smaller.
