NOTE: The wires and solder joints are small and delicate. If you don't have a suitable soldering
iron and a little expertise along these lines you may return your encoder housing to the factory
and we will make the change for you at no charge. Call first for a return authorization number
and instructions on how to return your housing.

the direction of the reading, unsolder and swap the green and black wires and then re-solder and
reassemble. (Click on photo to view larger image.)
Getting the most out of your DRO
When using a machine equipped with a digital readout, I find it is best to use either the readout
or the handwheels, but not both. If the displayed accuracy of .0005" (.01mm) is satisfactory for
the job you are doing, use just the digital readout and disregard the handwheel settings. In cases
where you might want to interpolate to a higher degree of accuracy, the markings on the
handwheels will allow you to do this.
An example of this would be where you have located the center of a bored hole and then changed
the table position. To return the spindle exactly to the hole's center again using the digital readout
could leave you a few ten-thousandths off, which may not be acceptable. In this case, you should
write down your handwheel settings and direction the handwheel was last turned before moving
from the desired location. This will allow you to return to the same spot with great accuracy. The
handwheel marks are .001" or .01mm apart. By reading the space between the marks on the
