Testing the Scales
Follow these steps to confirm that the scale has been installed properly.
The Counting Test will confirm the scale’s electrical operation, and the
Repeatability Test will check the installation integrity.
Counting Test
• Move the table along each axis, one at a time. Check that the
readout correctly displays the table’s movement. If it doesn’t,
then the scale resolution you selected may not be accurate. Refer
to Scale Resolution, pg. 9.
Repeatability Test
• Locate a magnetic base and dial indicator on the end of the scale.
Zero the readout and the indicator.
• Move the axis through the full travel and return the dial to “0.”
The readout should also read 0 (±0.0005” for 10µm scales;
±0.0002” for 5µm scales; ±0.00005” for 1µm scales). If it
doesn’t, then the scale cable may be loose, or the scale, mounting
bracket, or reading head may need to be tightened or realigned.
• Repeat these steps for each scale.
