5. The disc table rotates in the clockwise direction. The disc table rotation time is displayed with ‘’PLUS ONE” slit as a measuring point.
6. Measure the waveform of the oscilloscope when the disc table is rotating.
7. Move the holder (sensor) center so that the flat portion center at the top of the D.SENS (CH1) input waveform and the ‘’H” center of
HHOUT (CH2) coincide.
D.SENS (CH1) input waveform and the ‘’H” center of HHOUT (CH2) coincide.
10. If the adjustment is not successful, press the CLEAR button to rotate the disc table in the clockwise direction, and perform steps 6 to 9.
Note: During the adjustment mode, the rotational direction is switched each time the CLEAR button is pressed.
Pressing the CHECK button enters the loading mode which will be described later. Pressing the CLEAR button rotates the disc table
