(3) Adjust R415 (fig 1) until DEFLECTION ERROR indicates 7.3% HIGH, then
final adjust to center of 7.3% HIGH (R).
a. Performance Check
(1) Deenergize power module.
(2) Set TI DC
(down) position.
(3) Energize power module.
(4) Turn TI AMPLITUDE switch to 10.
(5) Connect frequency counter to TI AMPL OUTPUT. If frequency counter does
not indicate between 952.38 and 1052.6 hertz, perform b below.
b. Adjustments.
Adjust R587 (fig. 1) until frequency counter indicates 1.00
millisecond (R).

(1) Connect oscilloscope Vertical 1 input to TI AMPL OUTPUT, using 50
eedthrough termination.
(2) Turn PERIOD switch to 1 s and PULSE AMPLITUDE control fully
clockwise. Set mode switch to HIGH AMPL.
(3) Adjust oscilloscope for a stable display with vertical scale set to 1 V.
If
oscilloscope does not indicate at least 5 volts peak-to-peak, perform b below.
(4) Repeat (3) above for each PERIOD switch position.
(5) Remove termination from equipment setup.
(6) Turn PERIOD switch to 1 s. Oscilloscope display amplitude will be at least 60
volts peak-to-peak.
(7) Turn PULSE AMPLITUDE control fully counterclockwise.
Oscilloscope
display amplitude will be 6 volts or less.
b. Adjustments. Adjust R790 (fig. 1) until oscilloscope display indicates 5.2 peak-to-
peak (R).
a. Performance Check
(1) Connect TI positive FAST RISE OUTPUTS to oscilloscope Vertical 1 input
and TI negative FAST RISE OUTPUTS to oscilloscope Vertical 2 input.
(2) Turn TI mode switch to FAST RISE.
