1If
not within tolerance, perform b (3) and b (4) below.
2If
not within tolerance, perform b (5) and b (6) below.
b. Adjustments
(1) Adjust calibrator output for 1.9990 V.
(2) Adjust 2VAC (fig. 3) to obtain an indication of 1.999 on TI (R).
(3) Adjust calibrator output for 0.1999 V.
(4) Adjust .2VAC (fig. 3) to obtain an indication of 199.9 on TI (R).
(5) Adjust calibrator output for 19.990.
(6) Adjust 20VAC (fig. 3) to obtain an indication of 19.99 on TI (R).
a. Performance Check
(1) Press TI .2 range pushbutton.
(2) Connect calibrator current outputs to TI COM and MA/K
terminals.
(3) Adjust calibrator frequency to 400 Hz and current output to obtain an indication
of 199.9 on TI. Calibrator will indicate between 197.90 mA and 201.90 mA.
(4) Repeat (3) above with calibrator output frequency set to 60 Hz.
Calibrator
output will remain between 197.90 mA and 201.90 mA.
(5) Repeat technique of (1) through (4) above using settings and indications listed
in table 10. Calibrator will indicate within limits specified.
