Azimuth Adjustment - Sony LASERSCALE BS65-Serie Bedienungsanleitung

5-4-2. Azimuth Adjustment

A stable output signal higher than the specifications
(amplitude : 1.6 Vp-p) can be gained by adjusting the slider
direction.
Azimuth direction
1 Loosen the slider mounting screw.
2 Tighten either the left or right screw. Then, rotate the slider
about this screw as shown in the figure until you find the
point where the amplitude of the Lissajous' figure becomes
maximum.
3 Alternately tighten 2 slider mounting screws little by little at
the slider position with the maximum amplitude of the
Lissajous' figure. (Fastening torque : 2.8 N
4 Check to make sure the scale and slider are not interfering
with each other.

Scale
5 Move the scale, and make sure that the amplitudes A and
B of the Lissajous' figure (see the figure below) are 1.6 Vp-p
or greater over whole length.
Note
If output of 1.6 Vp-p cannot be obtained even through
repeated adjustment, recheck the mounting surface
accuracy of the scale and the slider (refer to page 21), and
check again that there is no dirt on the scale's surface.
