j. Adjust TI CH 1 VOLTS/DIV and VAR controls for exactly 4 divisions of vertical
display on CRT.
k. Disconnect TI CALIBRATOR output from CH 1 input.
l. Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 output to TI CH 1
input connector.
m. Set oscilloscope calibrator to a VOLTAGE output of 400 mV and frequency of 500 Hz.
n. Adjust oscilloscope calibrator knob located below the EDIT FIELD key for exactly 4
divisions displayed on TI CRT. Err displayed on oscilloscope calibrator will be within 1.0 percent.
o. Set oscilloscope calibrator output to minimum and disconnect equipment setup.
p. Select VAR and set CAL.
9. Vertical Gain Accuracy
NOTE
If TI does not perform as specified, perform adjustments as
indicated in SECTION IV.
a. Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 output to TI CH 1
input connector, oscilloscope calibrator SOURCE/MEASURE CHAN2 output to TI CH 2
input connector.
b. Rotate CH 1 VOLTS/DIV knob to set CH 1 for 2 mV indication in upper left portion
of CRT.
c. Set oscilloscope calibrator for a CHAN 1, VOLTAGE output of 10 mV and
frequency of 1 kHz.
d. Adjust TI VERTICAL
POSITION control to align bottom of signal 3 divisions
below CRT center graticule.
