TRACE
ROTATION
a. Position the
trace
to the center horizontal graticule
line.
b.
Check that the trace is parallel with the center
horizontal graticule line.
Readjust TRACE ROTATION if
necessary (front-panel screwdriver
adjustment).
2. Check ALT Mode
NOTE
VERT MODE switches are push-push
switches that
must be pressed to select a particular VERT
MODE
and pressed again to remove the
trace from
the
crt
display. For
example, selecting CH 1 VERT
MODE
does not release any VERT MODEs previously
selected, and the
CH
1
VERT
MODE switch must be
pressed again to remove the CH 1 trace from
the
display.
