a. Performance Check
(1) Connect TI VΩS and COMMON terminals to calibrator.
(2) Press TI range pushbutton settings and set calibrator output as specified in
table 5. TI will indicate within the specified limits.
b. Adjustments
(2) Set calibrator output to 100.00 mV. Adjust R15 (fig. 1) for a TI indication
slightly greater than 100.00 mV. Adjust R18 (fig. 1) for a TI indication of 100.00 mV (R).
