(a) Main Frame Controls. Set the main frame controls as
Turn the INTENSITY potentiometer to the fully counterclockwise
position. Then adjust the FOCUS potentiometer to the midrange
setting. Ensure that the BEAM FINDER switch is NOT pressed.
Now adjust the GRATICULE ILLUM potentiometer as desired.
Finally, ensure that the LEFT VERT MODE switch is depressed and
that the VERT MODE TRIG SOURCE switch is depressed.
Once the main frame controls are set according to the above
procedures, set the vertical amplifier controls.
(b) Vertical Amplifier Controls. Set the vertical amplifier
front panel controls as follows:
Turn the POSITION potentiometer to the midrange position. Then
place the POLARITY switch in the +UP position. With the
POLARITY switch in the +UP position, place the MAG switch to the
X1 position. Place the VOLTS/DIV switch to the 2V position and
turn the VARIABLE potentiometer/switch fully clockwise into the
switch detent. Finally, place the AC/GND/DC switch to the AC
Now that the vertical amplifier controls have been properly
controls as follows:
Move the LEVEL potentiometer to the midrange position and the
SLOPE indicator to the "+" position. Set the MODE switch to
AUTO, the COUPLING switch to AC, and the SOURCE switch to INT'.
Turn the POSITION and FINE potentiometers to the midrange
position. Press the XI MAC switch. Then set the TIME/DIV OR
DLY TIME switch to the 1 ms position and the delayed
time/division switch also to the 1 ms position. Turn the
VARIABLE potentiometer/switch clockwise to the switch detent.
Turn the DLY'D TRIG potentiometer/switch fully clockwise to the
RUNS AFTER DLY TIME position. Ensure that. the "+" SLOPE
pushbutton switch is pressed in, the AC COUPLING pushbutton
switch is pressed in, and the INT SOURCE pushbutton is pressed
in. Finally, set the DELAY TIME MULT potentiometer to the 1.00
