(6) Move multimeter positive lead to +15.4 V TP (fig. 9). If multimeter does not
indicate between 15.55 and 15.25 V dc, perform b (2) below.
(7) Move multimeter positive lead to +12.05V TP (fig. 9). If multimeter does not
indicate between 11.95 and 12.15 V dc, perform b (3) below.
(8) Set PWR-OFF-BATT switch to OFF, unplug from power and remove decade
resistor from battery terminals.
(9) Connect dc power supply and multimeter across battery terminals.
(10) Set power supply voltage for a 12 V reading on multimeter.
(11) Set PWR-OFF-BATT switch to BATT and slowly reduce dc power supply
voltage until TI just shuts off. If multimeter does not read between 10.9 and 11.1 V dc,
perform b (4) below.
b. Adjustments
(1) Adjust A1A22A1R41 (fig. 9) for an 18 V indication on multimeter (R).
(2) Adjust A1A22A1R6 (fig. 9) for a 15.4 V indication on multimeter (R).
(3) Adjust A1A22A1R55 (fig. 9) for a 12.05 V indication on multimeter (R).
(4) Adjust A1A14R22 (fig. 1) for a TI cutoff voltage of 11 V dc (R).
23. 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.
