(2) Move positive lead to TP401 (fig. 1). If multimeter does not indicate between
99.90 and 100.10 V, perform b (2) below.
(3) Move positive lead to TP402 (fig. 1). If multimeter does not indicate between
14.9 and 15.1 V, perform b (3) below.
(4) Move positive lead to TP403 (fig. 1). If multimeter does not indicate between
-
12.5 and -12.7 V, perform b (4) below.
(5) Connect multimeter between TP1 (fig. 1) and chassis ground. If multimeter
does not indicate between 99.9 and 100.1 V, perform b (5) below.
(6) Move positive lead to TP2 (fig. 1) and chassis ground. If multimeter does not
indicate between 14.90 and 15.10 V, perform b (6) below.
(7) Move positive lead to TP3 (fig. 1) and chassis ground. If multimeter does not
indicate between -12.5 and -12.7 V, perform b (7) below.
(8) Move positive lead to TP4 (fig. 1) and chassis ground. If multimeter does not
indicate between -99.9 and -100.1 V, perform b (8) below.
b. Adjustments
(1) Adjust R449 (fig. 1) for -100.00 V indication on multimeter (R).
(2) Adjust R412 (fig. 1) for +100.00 V indication on multimeter (R).
(3) Adjust R423 (fig. 1) for +15.0 V indication on multimeter (R).
(4) Adjust R434 (fig. 1) for -12.6 V indication on multimeter (R).
(5) Adjust R11 (fig. 1) for +100 V indication on multimeter (R).
(6) Adjust R20 (fig. 1) for +15.0 V indication on multimeter (R).
(7) Adjust R29 (fig. 1) for -12.6 V indication on multimeter (R).
(8) Adjust R40 (fig. 1) for -100.00 V indication on multimeter (R).
12. High Voltage Power Supply
a. Performance Check. Connect multimeter between TP301 (TP1 for models 180C
and D) (fig. 2) and chassis ground, using high voltage probe. If multimeter does not
indicate between -2935 and -2965 V for all models except models 180C and D, and -3135
and -3165 V for models 180C and D, perform b below.
b. Adjustments. Adjust R302 (fig. 2) for -2950 V indication on multimeter for all
models except models 180C and D. Adjust R49 (fig. 2) for V indication on multimeter for
models 180C and D.
13. Final Procedure
a. Deenergize and disconnect all equipment and reinstall protective cover on TI.
b. Annotate and affix DA label/form in accordance with TB 750-25.
