Turn on the machine.
Relate your measurement setup to the x-, or y- axis respectively. (See Fig. 8.9 - 3).
Adjust the oscilloscope.
Set the track signal tester to the "Oscilloscope cal" position.
With the help of the positioning switches CH1 and CH2, move the light spot exactly to the
center of the crosshairs of the screen.
Set the track signal tester to the "signal output" position.
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:

Turn the main switch to "ON".
Connect the track signal tester to the incremental encoder 1 of the x- / y- axis.
(See
Fig. 8.8 - 1).
NOTE
The testing sequences of the x- and y- axes are identical.

Set the track signal tester to selector switch "Oscilloscope cal.".
With the help of the positioning switch of CH 1, set the direct current signal on the center of the
upper half of the screen.
