The following procedure will prepare the Oscilloscope for
operation in any mode, and may be used at any time to
check the basic instrument operation.
2. Connect the line cord to an AC power source.
CAUTION: Do not permit a bright dot to remain on the
face of the cathode ray tube for a prolonged period of time;
a dot will burn the phosphors and leave a permanent image
in the face of the CRT.
3. Turn the INTENSITY control clockwise 1/3 of its
rotation.
4. Allow a minute or two for the instrument to warm up.
5. Slowly adjust the Y1 POSITION control and the
HORIZ POS control to center the trace on the screen.
6. Adjust the INTENSITY control to obtain a trace just
bright enough for your room lighting conditions.
7. Adjust the FOCUS control for the finest and sharpest
trace.
8. Adjust the HORIZ POS control so the trace starts at
the left edge of the graticule.
Your Oscilloscope is now prepared for operation in the
modes described in the “Operational Examples” section.
