b. Adjustments. Adjust calibrator output voltage to 19 V ac @ 20 kHz. Adjust C3 HF
ADJ (fig. 1) until TI indicates 19.00 V ac (R).
10. Dc Current Accuracy
a. Performance Check
(1) Connect TI MA input to calibrator OUTPUT HI and TI COMMON input to
calibrator OUTPUT LO.
(2) Press FUNCTION DC MA and RANGE 200 A pushbuttons.
(3) Set calibrator to 190 A. TI will indicate within limits specified in first row of
(4) Repeat technique of (2) and (3) above using settings listed in table 5. TI will
indicate within limits specified in table 5.
