13. Power Supply
a. Performance Check
NOTE
Do not perform power supply check if all other parameters are
within tolerance .
(1) Connect multimeter positive lead to TI PIN 12 (fig. 1) and negative lead to
chassis ground. If multimeter does not indicate between 30.8 and 31.2 V, perform b
(1) below
(2) Move positive lead to PIN 13 (fig. 1). If multimeter does not indicate between -
25.5 and -26.5 V, perform b (2) below.
b. Adjustments
(1) Adjust A1R14 (fig. 1) for a +31 V indication on multimeter (R).
(2) Change the value of R15 (fig. 1) to obtain the required voltage (increasing the
value of A1R15 makes the power supply less negative, and vice versa.
14. Final Procedure
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.
