b. Adjustments. Ensure that dc power supply output is 36 (1) V dc; otherwise, no
adjustments can be made.
9. Ac Voltage and Frequency
a. Performance Check
(1) Configure multimeter for most accurate ac voltage measurements.
(2) Connect multimeter INPUT HI to TI TP7 and LO to TP9. Multimeter will
indicate between 9.9940 and 10.0060 V ac; if not, perform b (l) below.
(3) Move multimeter INPUT HI test lead to TI TP8.
Multimeter will indicate
between .99940 and 1.00060 V ac; if not, perform b (2) below.
(4) Press multimeter FREQ pushbutton.
(5) Multimeter will indicate between 19.8 and 20.2 kHz.
(6) Reduce calibrator and dc power supply outputs to minimum.
b. Adjustments
(1) Adjust 10 V ac adjustment (fig. 2) for a 10.0000 V (1.0 mV) indication on
multimeter (R).
(2) Adjust 1 V ac adjustment (fig. 2) for a 1.00000 V (0.1 mV) indication on
multimeter (R).
