(12) Adjust DC CONTROL for a 28 V dc indication on TI voltmeter.
(13) Using standard measurement technique, measure the ripple voltage with
oscilloscope. The ripple voltage as indicated by oscilloscope will not exceed 2 V p-p.
(14) Set DC CONTROL fully ccw and set 6 AMP POWER circuit breaker OFF.
Disconnect dc load and oscilloscope from TI.
(15) Set 6 AMP POWER circuit breaker to ON and set TEST CONDITION switch
to VOLTS.
(16) Connect multimeter to MODE C ENCODER J5 pin s and chassis ground, using
appropriate leads.
(17) Adjust DC CONTROL for a 28 V dc indication on TI voltmeter. Multimeter will
indicate between 1 and 2 V dc.
(18) Set all MODE C ENCODER SIMULATOR switches to OFF.
(19) Multimeter will indicate between 18.5 and 21.5 V dc.
(20) Disconnect multimeter from pin s and connect to pins g, b, f, m, p, J, L, P, T, and
F respectively. Multimeter will indicate as specified in (19) above for each pin.
(21) Set DC CONTROL fully ccw and 6 AMP POWER circuit breaker OFF.
b. Adjustments. No adjustments can be made
a. Performance Check
(1) Connect equipment as shown in figure 3.
(2) Set pulse generator controls for a positive (+) pulse output at a 1 kHz rate.
(3) Adjust pulse generator controls for a 0.5 s pulse 10 V in amplitude as indicated
on oscilloscope CH 2.
(4) Set 6 AMP POWER circuit breaker to ON and adjust DC CONTROL for a 28
V dc indication on TI voltmeter.
(5) Using standard measurement techniques, measure the pulse characteristics
listed in table 4 for the REPLY pulse on CH 1 of oscilloscope. Indications as observed on
oscilloscope will be as specified in table 4.
