(5) If TI voltage dials do not indicate between 9.999690 and 10.000310, perform
b(1) and (2) below.
(6) If TI voltage dials are within tolerance but not exactly 10.000000, perform b(3)
below.
(7) Set dc transfer standard for a 10-volt mean output.
(8) Set voltage divider to .999999X.
(9) Adjust TI voltage dials for a null indication on null detector.
(10) Record TI dial indication for future use.
This is the actual value of 10-volt
output of dc transfer standard.
(11) Set dc transfer standard for 1.018 + ∆E, mean output and sets ∆E dial to 000.
(12) Set TI voltage dials to 8.888888.
(13) Adjust voltage divider for a null indication on null detector.
(14) Voltage divider will indicate between .1145215 and .1145286.
(15) Repeat technique of (12) through (14) above, using settings and indications
listed in table 5. Set TI POWER switch to STANDBY/RESET.

(16) Set voltage divider to one-hundredth of value recorded in (10) above.
(17) Set dc transfer standard for a 10-volt mean output.
(18) Position TI controls as listed in (a) through (c) below:
(a) VOLTAGE RANGE to 100.
(b) Voltage dials to 100.000000.
(c) POWER switch to ON.
(19) Adjust TI voltage dials for a null indication on null detector.
