Å Turn on the machine.
Å Relate your measurement setup to the x-, or y- axis respectively. (See fig 6.5 - 3).
Å Adjust the oscilloscope.
Å Set the track signal tester to the "Oscilloscope cal" position.
Å With the help of the positioning switches CH1 and CH2, move the light spot exactly to the
center of the crosshairs of the screen.
Å Set the track signal tester to the "signal output" position.
Å Manually, move the appropriate axis (x = head / y = gantry) back and forth.
– If you adjusted the read head correctly, the following illustration will appear on the screen of
the oscilloscope:
