(1) Set TI voltage dials to 10.000000.
(2) Adjust R804 (fig. 3) for a null indication on null detector (R).
(3) Perform (1) and (2) above, but do not report adjustments.
(4) TI voltage dials to 100.00000.
(5) Adjust R806 (fig. 3) for a null indication on null detector (R).
(6) Perform (4) and (5) above, but do not report adjustment.
(7) Set TI voltage dials to 1000.0000.
(8) Adjust R808 (fig. 3) for a null indication on null detector (r).
11. Panel Meter, Voltage Trip, and Current Limit
a. Performance Check
(1) Disconnect TI from equipment setup.
(2) Set VOLTAGE RANGE switch to 10, POWER switch to ON, and voltage dials
for indication of 10 on 0-to-12 scale of panel meter.
(3) If voltage dials do not indicate between 9.700000 and 10.300000, perform b(1)
and (2) below.
(4) Set voltage dials to 6.000000.
(5) Slowly turn VOLTAGE TRIP control counter clockwise until voltage trip circuit
actuates. If the VOLTAGE TRIP control is not an approximately midrange, perform b(3)
through (7) below.
(6) Set POWER switch to STANDBY/RESET.
(7) Connect decade resistor (A3) to OUTPUT terminals and adjust to 100 ohms.
(8) Position TI controls as listed in (a) through (d) below:
(a) METER switch to CURRENT.
(b) Voltage dials to 0000000.
(c) VOLTAGE TRIP control fully clockwise.
(d) POWER switch to ON.
