(1) TIME/DIV switch to 0.5 ms.
(2) COUPLING pushbutton to AC.
(3) SOURCE pushbutton to INT.
(4) MODE pushbutton to AUTO.
(5) TIME/DIV or DLY TIME VARIABLE control to CAL.
(6) +SLOPE- pushbutton to +SLOPE.
(7) MAGNIFIER pushbutton to X1 (IN).
d. Position oscilloscope VERT MODE pushbutton to LEFT and TRIG SOURCE
pushbutton to LEFT.
e. Set oscilloscope POWER (ON/OFF) switch to ON and allow at least 20 minutes
for warm-up.
15. Gain and Attenuator Accuracy
a. Performance Check
(1) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 to TI +INPUT jack.
(2) Press oscilloscope calibrator VOLTAGE key and set for a 5 mV, 1 kHz output.
If oscilloscope does not display 5 divisions of vertical deflection, adjust TI GAIN (front
panel) for 5 divisions.
(3) Turn oscilloscope calibrator EDIT FIELD knob to bring up oscilloscope
calibrator err display.
(4) Set TI and oscilloscope calibrator to values listed in table 7 and adjust
oscilloscope calibrator EDIT FIELD knob for number of divisions of vertical deflection
shown in table. Oscilloscope calibrator err display will be within 2 percent of output
specified in table 7.
b. Adjustments. No further adjustments can be made.
