(4) and (5) above to establish calibrator reference; then repeat (6) above for remaining
frequencies.
9. Ac to Dc Converter Output
a. Performance Check
(1) Connect calibrator OUTPUT terminals to TI INPUT terminal and multimeter
INPUT to TI rear panel DC OUTPUT terminals.
(2) Set RANGE switch to .01 VOLTS and set calibrator for a 10 mV, 1.0 kHz
output. If multimeter does not indicate between 0.9950 and 1.0050 V dc, perform b below.
10. Final Procedure
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.
