► To check the track signals, connect the track signal tester and the oscilloscope. (See "6.3.1.1 Meas-
uring the Analog Zero Pulse Signal" [ ➙ 212].)
Oscilloscope settings: Connect CH1 to track A, CH2 to track B.
► Switch the machine on.
► Switch the track signal tester to Calibrate oscilloscope.
► Set both oscilloscope channels to GND. Place the lines for CH1 and CH2 over one another (on the
zero line of the coordinate system).
► Set both channels to DC, Refr., Non Store, Autotrigger (20 ms).

► Voltages V/Division decrease up to 0.5 V/Div.
► Set the track signal tester switch to "Measure".
► Switch the oscilloscope to X/Y --> Illuminated point will appear!
► Move the point into the middle of the display.
► Manually move the selected axis back and forth.
Analog track signals A and B in X/Y oscilloscope mode
► The adjacent picture should appear on the oscillo-
scope.
NOTICE! A new version of the incremental en-
coder (one field lens) can recognize signals from 1.8 to
3.6 Vss.
Analog track signals 90° phase shift
► Switch the oscilloscope from X/Y deflection to normal
mode.
► The adjacent picture should appear on the oscillo-
scope.
