(4) Push in X10 MAG switch. If first marker does not remain aligned behind center
vertical graticule line within 1 minor division, perform b below.

11. Sweep Timing
a. Performance Check
(1) Set oscilloscope calibrator MARKER output to 1 ms, and set TI VOLTS/DIV
switch for approximately 4 divisions of vertical display.
(2) Adjust TRIGGERING LEVEL control for a stable display and horizontal
calibrator knob located under the EDIT FIELD key to align 10th marker behind 10th
vertical graticule line. If Err displayed on oscilloscope calibrator does not indicate within
limits shown in the first row of table 6, perform b (1) below.
(3) Repeat technique of (1) and (2) above for TIME/DIV and oscilloscope calibrator
MARKER outputs listed in table 6. If oscilloscope calibrator Err displayed does not
indicate within limits shown in table 6 at each setting, perform b (1) through (3) below.
