➠ Turn on the machine.
➠ Relate your measurement setup to the x-, or y- axis respectively. (See ).
➠ 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:

NOTE
The pulse width of the analog zero pulse is dependent on the speed at which the axis is
traversed.

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