Azimuth Adjustment - Sony BL55-NE Bedienungsanleitung

3-5-2. Azimuth Adjustment

The direction shown in the figure below is referred to as the azimuth direction. A stable output signal of the
specified value or higher can be obtained by adjusting the detector head direction.
<Standard values>
A/B signal output type ...... Output format A
Analog output type ........... Amplitude 0.3 Vp-p
Azimuth direction
1
Loosen the detector head mounting screws.
2
Rotate the detector head as shown in Fig. 3-13, until you find the point where the amplitude of the
Lissajous' figure is at a maximum.
3
Alternately tighten the two detector head mounting screws little by little at the detector head position
with the maximum amplitude of the Lissajous' figure. (Fastening torque: 0.8 N . m)
4
Check that there is no interference between the scale and detector head.
