(5) Ensure that VOLTAGE RANGE switch is set to 10 V and VOLTAGE dials to
1.00000 V (1 MHz).
(6) Adjust A8R89 for the same error as recorded in step 4 of table 6 (10 V, 1 MHz) 0.2% (R).
(7) Repeat technique of steps 4 and 5 of table 6 and b (5) and (6) above until they
can be performed without adjustments.
(8) Adjust A8R91 for best null indication on multimeter (R).
(9) Adjust A6C3 for a 0.033 ( 5 digits) indication on multimeter (R).
12. Power Supply
NOTE
Do not perform power supply checks if all other parameters are
within tolerance.
a. Performance Check
(1) Connect multimeter to REGULATOR A5A2TP8 (HI) and A5A2TP5 (LO) (fig. 1)
(2) Set MODE switch to OPER. If the multimeter does not indicate between 14.99
and 15.01 V dc, perform b (1) below.
(3) Move multimeter (HI) lead from REGULATOR A5A2TP8 to A7TP3 (fig. 1). If
multimeter does not indicate between 185 to 200 V dc, perform b (2) below.
(4) Set MODE switch to STDBY.
b. Adjustments
0.01 V dc indication on
(1) Adjust REGULATOR A5A2R32 (fig. 1) for a 15
multimeter (R).
(2) Adjust REGULATOR A5A2R32 (fig. 1) for a minimum indication on multimeter
of 185 V up to 220 V dc (R).
13. Final Procedure
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.
