NOTE
Interaction occurs between R1145 and R1115 (fig. 1). Readjust
as necessary for best in-tolerance condition. On some models
R1115 is labeled R813.
(1) Set DELAY TIME POSITION dial to 1.00. Adjust R1115 (fig. 1) to align start
of signal with start of sweep trace (R).
(2) Set DELAY TIME POSITION dial to 9.00. Adjust R1145 (fig. 1) to align start
of signal with start of sweep trace (R).
(3) Set oscilloscope calibrator for MARKERS at 1 ms and adjust R1257 (fig. 2) for 1
marker per division (R).
(4) Set oscilloscope calibrator for MARKERS at .1 ms and adjust R1253 (fig. 2) for
1 marker per division (R).

(5) Set oscilloscope calibrator for MARKERS at 1 ms and adjust R1175 (fig. 1) for
1 marker per division (R).
NOTE
