(26) Adjust DELAY TIME MULT dial to 9.00.
(27) Adjust POSITION control to align the leading edge of time marker to the center
vertical graticule line.
(28) Decrease DELAY TIME MULT dial (near 8.0) to align the leading edge of time
marker to the center vertical graticule line. DELAY TIME MULT dial will indicate
between 7.94 and 8.06.
(29) Repeat technique of (28) above for DELAY TIME MULT dial settings and
indications listed in table 6.
