b. Adjustments
(1) Set NULL switch to TVM and voltage dials to 10.00000.
(2) Set NULL switch successively to each more sensitive position while adjusting
R120 (fig. 1) for a null indication on TI (R).
(3) Set NULL switch to TVM and voltage dials to 1.000000.
(4) Set NULL switch successively to each more sensitive position while adjusting
R122 (fig. 1) for a null indication on TI (R).
(5) Set NULL switch to TVM and voltage dials to 100.0000.
(6) Set NULL switch successively to each more sensitive position while adjusting
R103 (fig. 1) for a null indication on TI (R).
a. Performance Check
(1) Utilizing the dc reference standard and standard resistor, characterize
multimeter to obtain 24-hour manufacturer specifications.
NOTE
If ambient temperature drifts more than 1 degree Celsius prior
to completing paragraph 9, the characterization and paragraph
9 must be repeated.
(2) Short INPUT and COMMON terminals.
(3) Position controls as listed in (a) through (c) below:
(a) RANGE switch to 1.
(b) Readout dials to 000000.
(c) NULL switch to .0001.
(4) Adjust electrical ZERO control for a 0 meter indication; then remove short from
INPUT and COMMON terminals.
NOTE
Set NULL switch to TVM prior to changing input voltage or
changing other TI switch positions.
(5) Position controls as listed in (a) through (c) below:
(a) RANGE switch to 10.
(b) Readout dials to 10.00000.
