b. Adjustments. No adjustments can be made.
8. Ratio Accuracy
a. Performance Check
(1) Connect equipment as shown in figure 1.
(2) Position TI outer dial to 10 and inner dial to 0.
(3) Adjust voltage divider (A3) to 9900000.
(4) Adjust output of voltage standard (A4) to 5 volts.
(5) Set TI outer dial to 9 and inner dial to 90.
(6) Adjust voltage divider dials to obtain null on null detector (A1). Voltage divider
will indicate between 98900 and 99100. If not, perform b below.
(7) Repeat technique of (5) and (6) above at TI dial settings listed in table 5.
Voltage divider will indicate within limits specified. If not, perform b. below to obtain best
in-tolerance compromise of error across entire TI range.
