(9) Adjust voltage dials for indication of 60 milliamperes on panel meter.
(10) If voltage dials do not indicate between 5.820000 and 6.180000, perform b(8)
through (11) below.
(11) Set POWER switch to STANDBY/RESET.
b. Adjustments
WARNING
Dangerous potentials exist between chassis and ground.
Exercise extreme caution.
(1) Set voltage dials to 10.000000.
(2) Adjust R210 (fig. 3) for null indication on null detector (R).
(3) Set VOLTAGE TRIP control fully clockwise.
(4) Set POWER switch to STANDBY/RESET and back to ON.
(5) Adjust R213 (fig. 3) fully counterclockwise.
(6) Set VOLTAGE TRIP control to midrange.
(7) Slowly adjust R213 clockwise until voltage trip circuit actuates (R).
(8) Set voltage dials to 6.000000.
(9) Adjust R617 (fig. 3) fully counterclockwise then clockwise until LIMIT ON lamp
comes on. Panel meter should indicate 60 milliamperes (R).
(10) Turn CURRENT LIMIT control to 0 (zero).
(11) Adjust R615 (fig. 3) for indication of 1 milliampere on panel meter (R).
a. Performance Check
NOTE
Do not perform power supply checks if all other parameters are
within tolerance.
