Conned o test lead from fhe CAL. OUT connector to the
A input connector; this should result in a free-running trace
having an amplitude of one minor graticule division (one-
fifth of major division). Center the traco vertically on the
screen and adjust the INTENSITY, FOCUS and ASTIGMATIM
controls for best definition. Then ground the junction of R19,
R20, and R2I with a short clip lead. This junction is located
on tho Trigger switch (see Fig. 6-6).
8. TRIG. LEVEL CENTERING R39.
Set the TRIG. SENS, con
trol fully counterclockwise and the TRIG. LEVEL CENTERING
control fully clockwise. Turn the STABILITY control counter
clockwise until the trace just disappears from the ert screen,
then two or three degrees further counterclockwise.
Rotate the TRIG. LEVEL CENTERING control slowly coun
terclockwise until the trace appears (it may just flicker), then
back off the control approximately 2 degrees clockwise from
that point.
Whenever you adjust the TRIG. LEVEL CENTERING ad
justment you should also adjust the TRIG. SENS, as described
in the following step.
9. TRIG. SENS. R47-
(Always perform step 8 before this
step). Leave the jumper wire and calibrator signal connected
as in fhe previous step. Rotate the TRIG. SENS, control slowly
clockwise until the sweep triggers. Rotate the TRIG. LEVEL
CENTERING control until stable triggering is obtained with
the black TRIGGER SELECTOR control in both the -f-INT,
and —INT. position. Rotate the TRIG. SENS, control clock
wise until unstable triggering occurs, then back off a few
degrees into a stable region. Check that the sweep is trig
gered on the - f slope of the calibrator woveform when the
black TRIGGER SELECTOR control is set at + INT., and on
the — slope when the switch is set at —INT. If the slopes
ore reversed, reset the TRIG. SENS, and TRIG. LEVEL CEN
TERING controls slightly until the slopes are correct and
stable triggering is obtainod. Perform the next step im
mediately.
10. INT. TRIG. DC LEVEL R3.
