(2) Adjust dc voltage standard (A2, table 6) for full-scale indication on UUT meter.
(3) Turn NULL switch to 10, 1, .1, and .01 while adjusting dc voltage standard for 0
(zero) indication on UUT meter. Dc voltage standard will indicate between 49.975 and
50.025 volts. If not, perform b below.
(4) Turn NULL switch to VTVM.
(5) Adjust dc voltage standard for 0 (zero) indication on UUT meter.
b. Adjustments
(1) Turn NULL switch to VTVM.
(2) Adjust dc voltage standard for 50.000 volts.
(3) Turn NULL switch to 10, 1, .1 and .01 while adjusting R323 (fig. 2 or 3) for
0 (zero) indication on UUT meter.
