(3) Set calibrator initial output for 250 mV. Adjust calibrator output controls for a
0.25 V dc TI indication. Calibrator control Error display will indicate within +3 percent.
(4) Repeat technique of (2) and (3) above for TI function/range switch and calibrator
output settings listed in table 3. Calibrator control Error display will indicate within
+3 percent for each TI indication.

(1) Connect calibrator output to TI + and COM.
(2) Set TI function/range switch to 50 A.
(3) Set calibrator initial output for 50 A. Adjust calibrator output controls for a 50 A
indication on TI. Calibrator control Error display will indicate within +3 percent.
(4) Repeat technique of (2) and (3) above for TI function/range switch and calibrator
initial output settings listed in table 4. Calibrator control Error display will indicate
within +3 percent for each TI indication.
