Press the Select Key next to the ‘X’, ‘Y’ or ‘z’ to cycle through
the available settings for each axis.
Radius / diameter
The Diameter setting is useful for lathes, and other turning
applications to display the diameter reading rather than the
radius.
When you select the Diameter setting the C80 displays double
the actual movement on any axis.
There are two settings for each axis:
Press the Select Key next to the ‘X’, ‘Y’ or ‘z’ to cycle through
these settings.
Direction
You use the Direction setting to match the C80 to the actual
direction of travel of any axis.
There are two settings for each axis: ‘dir. 0’ and ‘dir. 1’.
Press the Select Key next to the ‘X’, ‘Y’ or ‘z’ to cycle through
these settings.
The Direction setting is arbitrary. You should set it to whichever
option makes most sense for the machine.
The Direction depends on where the scale is mounted.
Error compensation
Your digital readout (DRO) system helps you to improve
productivity. It decreases the number of scrapped parts, as you
no longer have to be concerned about making mistakes related
to counting the revolutions on the dials. Your DRO system also
helps to eliminate some errors related to ballscrew backlash.
Your DRO system will operate to its published accuracy,
provided all components are in working order and properly
installed. Field calibration is not necessary.
Accuracy problems with machined parts may be caused by
machine error, DRO system error, or a combination of both. The
first step in determining the source of error is to check the DRO
system. You do this by comparing the movement of the Newall
reader head to the position reading shown on the display. You
