7. Move the holder (sensor) center so that the flat portion center at the top of the SENS (CH1) input waveform and the ‘’H” center of
TEST (CH2) coincide.
8. Tighten the fixed screw to fix the disc table, then press the [CLEAR] button.
9. The disc table rotates in the counterclockwise direction. Measure the waveform and make sure that the flat portion center at the top of
the SENS (CH1) input waveform and the ‘’H” center of TEST (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 again.
