(24) Adjust TI voltage dials for null indication on each successively more sensitive
position of NULL switch until null indication is obtained on the most sensitive position.
(25) Final TI indication will be between 999.971 and 1000.029.
(26) Set calibrator to STANDBY; then press RESET pushbutton.
(27) Connect equipment as shown in figure 3.
Set dc voltage divider dials to
0.1111111 and TI RANGE switch to 10.
Figure 3. Voltage dial accuracy.
(28) Set calibrator for a 10.0 V dc output. Adjust TI voltage dials for null indication
on each successively more sensitive position of NULL switch until null indication is
obtained on the most sensitive position. Final TI indication will be between 1.11107 and
1.11115.
(29) Repeat technique of (28) above for dc voltage divider settings listed in table 5.
Final TI voltage dial indications will be within the specified limits.
