Remove the stopper from the detector head.

Move the scale, and make sure that the amplitudes A and B (see Fig. 3-18) of the Lissajous' figure are
within the range of the specified values over the entire length.
<Specified values>
A/B signal output type ..... Output format F : Amplitude 0.7 Vp-p to 1.3 Vp-p
Analog output type ........... Output format H : Amplitude 0.6 Vp-p to 1.1 Vp-p
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 to 3-4), and check again that there is
no dirt on the scale's surface.

(E)
Do not move the machine device with
the stopper attached to detector
head because this may result in
breakage of the detector head or the
scale.
