f.
Remove signal from X input terminals.
g.
Apply 0.7 Vdc (0.9 Vdc) to Y input terminals.
h.
Adjust R126 to position pen to full scale.
i.
In the event full scale cannot be reached by using
calibration controls, check electronic reference for output of 9.0
volts

5%.
5-96. PHASE SHIFT ADJUSTMENT
5-97. Assuming both X and Y axes have been adjusted by
means of the retrace curves described in paragraph 5-91, the
attenuator switches may be set to identical values in both X
and Y to produce a straight line of 45 degree angle. If the
retrace test made on X and Y demonstrates zero trace, the gap
which appears in the 45 degree retrace line will be due to a
phase difference or time lag between the two recording axes.
Phase adjust is accomplished by adjusting R114. Access to
R114 is obtained by removing bottom cover. See
paragraph 5-18 and Figure 5-24.
