(12) Adjust the autotransformer until the meter indicates 115 V ac.
(13) Using TI front panel controls, program voltage and current outputs for 0.
No adjustment can be made for 1791; for all others see

a. Performance Check
(2) Set the decade resistor resistance for maximum current at maximum voltage
(3) Using TI front panel controls, program voltage and current outputs for full scale
(4) Reduce the decade resistor resistance until TI front panel display indicates full
scale A and ensure CC enunciator is illuminated.
NOTE
In the following step, if TI does not remain in the CC mode,
decrease the decade resistor resistance until TI CC enunciator
remains on.
(5) Divide the multimeter indication by the DC current shunt certified resistance
and record results.
