(14) Disconnect digital multimeter from TI and adjust ∆REF OR DLY POS control
to intensify 2d time marker.
(15) Adjust ∆ control to intensify 10th time marker and superimpose delayed B
sweep time markers within .2 division.
(16) Push up and release TRIGGER COUPLING switch.
(17) Display readout will indicate ADJ ∆, (step) 3, 300 s, 1 s.
(18) Adjust ∆REF OR DLY POS control to intensify 4th time marker and ∆ control
to intensify 28th time marker and superimpose delayed B sweep markers within 1.2
division.
(19) Push up and release TRIGGER COUPLING switch.
NOTE
If adjustments are made in (18) above, display readout will
indicate ADJ ∆ (step) 2, 200 s, 1 s. Repeat (14) through (19)
above until no adjustments are made in (18) above.
(20) If no adjustments were made in (18) above, display readout will indicate ADJ ∆,
(step) 4, 100 s, 1 s.
(21) Change oscilloscope calibrator MARKER mode output to 5 S/D.
(22) Adjust ∆ control ccw until no further movement of B sweep display occurs. Note
position of first time marker of B sweep.
(23) Adjust ∆ control cw until 2d time marker of B sweep moves left and aligns with
position noted in (22) above.
NOTE
Movement of ∆REF OR DLY POS control at this point will
(24) Push up and release TRIGGER COUPLING switch. Display readout will
indicate X1, X10, HRZ CTR, (step) 5, 10 s and two vertical cursors appears on the
display.
(25) Change oscilloscope calibrator MARKER mode output to 10 S/D.
(26) If cursors are not aligned with 2d and 10th vertical graticule lines, adjust
Xl GAIN (R860) (fig 1), and HORZ CTR (R801) (fig 1) to align the two cursors with 2nd and
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) Push up and release TRIGGER COUPLING switch.
Display readout will
indicate ADJ ∆, (step) 6, 10 ms, 100 s.
(29) Change oscilloscope calibrator MARKER mode output to 10 mS/D and adjust
∆REF OR DLY POS control to intensify 2d time marker and ∆ control to intensify 10th
time marker, and superimpose delayed B sweep time markers within .2 division.
