(3) Adjust TI ⇐POSITION⇒ control to align 1st time marker with 1st (extreme left)
vertical graticule line.
(4) Adjust R740 (fig. 1) for 1 time marker per division over center eight divisions
(R).
(5) Set TI HORIZONTAL MODE switch to B and adjust B INTENSITY control
for suitable viewing. Adjust TI ⇐POSITION⇒ control to align 1st time marker with 1st
vertical graticule line.
(6) Adjust R730 (fig. 1) for 1 time marker per division over center eight divisions
(R).
(7) Set TI HORIZONTAL MODE switch to A and pull X10 CAL control to out
position.
(8) Set oscilloscope calibrator MARKER output to 10 S/D.
(9) Adjust TI ⇐POSITION⇒ control to align nearest time marker to 1st vertical
graticule line.
(10) Adjust R754 (fig. 1) for 1 time marker per division (R).
(11) Set TI A AND B SEC/DIV switches to .2 ms.
(12) Set oscilloscope calibrator MARKER output to 1 mS/D.
(13) Adjust TI ⇐POSITION⇒ control to position middle time marker to center
vertical graticule line.
(14) Push TI X10 CAL control to in position.
