6 . 5 Readout Accuracy
The accuracy of your digital readout system is dependent on many
items. Factors such as stage accuracy and condition, scale accuracy
and condition, method of inspection and operator interpretation. All will
determine the outcome of any accuracy test. Although this is an
operations manual and is not intended to serve as a calibration manual;
we have outlined the basics of inspection and compensation below.
Inspect condition of system and repair/ replace as required.
Test mechanical repeatability and geometry of stage. Adjust as
required.
Test repeatability of scale-DRO, adjust, replace or return to above
steps.
Inspect accuracy of reading using a certified standard of known
dimension. If reading is within specifications the procedure is complete.
If reading is not within specifications,
remove all readout compensation
and re-inspect. Re-compensate as required per instructions of your
separate digital readout manual.
6 . 6 Lubrication
Never spray lubricant directly onto the machine. Oil mist can
collect on the measuring scales or reading head and affect
performance. Lubrication can be performed once a year on most
machines. If your machine is in a very dirty environment or is used
excessively you should lubricate two times per year.
