Move the scale, and make sure that the amplitudes A and B (see Fig. 3-15) of the Lissajous' figure are
the standard values or greater over the entire length.
<Standard values>
A/B signal output type ..... Output format A
Analog output type ........... Amplitude 0.3 Vp-p
For output format A, the center of the Lissajous' figure is 0 V. For output format F, G, and H, the center
of the Lissajous' figure is 2.5 V.
If the output of 1 Vp-p cannot be obtained even through repeated adjustment, recheck the mounting
surface accuracy of the scale and detector head (refer to pages 3-3), and check again that there is no dirt
on the scale's surface.

. Secure the cable with the supplied cable clamp and pan-head screw (M4 x 8).
. Before using the scale to perform measurements, allow the scale to set for about three hours after mount-
ing so that the secured parts can stabilize and the ambient temperature around the scale can stabilize.
