Summary  The process shoul d be repeated until both the X and Y axes look like the photo, both in the pre-placement and placed position.

X-Axis Correction

The screw is sensitive !!!!!

• Look through microscope – scales should be aligned

• Turn screw in a direction that moves scale A in the direction of the error (green

arrow)

• Stop when the scales read an offset the same as the error ( 3µm left in the example)

• Looking through the microscope now adjust the x-axis micrometer so that the scales

are once again aligned

• Repeat the placement procedure to check the X-axis alignment

• Note the new error

• Repeat the adjustment procedure until error is 1 micron or less

Y-Axis Correction

The screw is sensitive !!!!!

• Look through microscope – scales should be aligned

• Turn screw in a direction that moves scale A in the direction of the error (blue arrow)

• Stop when the scales read an offset the same as the error ( 4µm down in the example)

• Looking through the microscope now adjust the Y-axis micrometer so that the scales are

once again aligned

• Repeat the placement procedure to check the Y-axis alignment

• Note the new error

• Repeat the adjustment procedure until error is 1 micron or less

Summary

 The process should be repeated until

both the X and Y axes look like the

photo, both in the pre-placement

and placed position.
