(26) If cursors are not aligned with 2d and 10th vertical graticule lines, adjust XI
10th vertical graticule line (R).
(27) If TI does not display 1 time marker per division l minor division, adjust X10
GAIN R850 (fig. 1) for 1 marker per division (R).
(28) Press and release upper TRIGGER COUPLING pushbutton. Display readout
will indicate: ADJ ∆, (step) 6, 10 ms, 100 s.
(29) Set oscilloscope calibrator MARKER output to 10 S/D and adjust ∆REF OR
DLY POS control to intensify 2d time marker, adjust ∆ control to intensify 10th time
marker, and superimpose delayed sweep time markers within .2 division.
(30) Press and release upper TRIGGER COUPLING pushbutton, and set
oscilloscope calibrator output for 1 mS/D.
(31) For each step in table 20 do the following:
(a) Adjust ∆REF OR DLY POS and ∆ controls, as necessary, to intensify
indicated time markers on the A sweep and superimpose displayed B sweep time markers
within listed limits.
(b) Press and release upper TRIGGER COUPLING pushbutton.
