f. Disconnect the input signal.
g. CHECK-=-CRT display for straight line near the center
horizontal line.
15. Check Low-Frequency Linearity
a. Reconnect the standard amplitude calibrator to the
vertical INPUT connector with the 42 inch BNC cable.
b. Set the standard amplitude calibrator for a 0.5-volt
square-wave output.
c. Position the display to the center of the graticule
with the VER TICA L POSITION control.
d. Reduce the display to exactly two divisions with the
Variable VO LTS /D IV control (keep display centered about
the center horizontal line).
e. Position the top of the display to the top horizontal
line of the graticule.
NOTE
Tolerances given in this step are typical values pro
vided as guides to correct instrument operation, and
are not instrument specifications.
f. CHECK- Vertical compression of display does not
exceed 0.1 division or expansion does not exceed 0.15
division.
g. Position the bottom of the display to the bottom
horizontal line of the graticule.
h. CHECK-Vertical compression of display does not
exceed 0.1 division or expansion does not exceed 0.15
division.
i. Set the Variable VO LT S /D IV control to C A LI
BRATED.
j. Disconnect all test equipment.
16. Adjust Hum Balance
PERFORMANCE CHECK ONLY
This step is not applicable to a performance check.
Proceed to next equipment required picture (Fig.
5-11).
a. Set the VO LT S /D IV switch to .01.
b. Connect the vertical INPUT connector to one of the
ground posts on the front panel with the 18-inch BNC-to-
banana plug patch cord.
c. Connect the 10X probe to the test oscilloscope input
connector.
d. Set the test oscilloscope for a vertical deflection
factor of 0.05 volts/division (0.5 volts/division at probe
tip), AC coupled, at a sweep rate of five milliseconds/
division.
e. Connect the 10X probe tip to the hum balance test
point (see Fig. 5-10A). Connect the probe ground strap to
the Type 310A chassis near the test point,
f. ADJUST—Hum Balance adjustment, R470 (see Fig.
5-10B), for minimum vertical deflection on the test oscillo
scope.
g. Disconnect all test equipment.
