(3) Repeat (1) and (2) above and adjust R2 (fig. 3) for best compromise or until no
further adjustments are required.
(4) With TI HI and LO terminals shorted rotate generator crank cw at normal
speed and adjust R1 (fig. 3) for 0 .045 inches.
(5) Remove short and reconnect resistance standard, rotate generator crank cw at
normal speed and adjust R1 (fig. 3) for 50 MΩ .045 inches.
(6) Repeat (4) and (5) above and adjust R1 (fig. 3) for best compromise or no further
adjustments are required.
17. 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.
