If you adjusted the read head correctly, the following illustration will appear on the screen of the
oscilloscope:

(1) No spurious peaks are allowed in this measuring range.
NOTE
Check the analog signal of the zero pulse, to ascertain that the zero pulse is discerned correctly.
If the zero pulse is not discerned correctly, the axis will reference to a spurious peak.
Placement offsets will be the result.
The pulse width of the analog zero pulse is dependent on the speed at which the axis is
traversed.
