9. Regulator
a. Performance Check
(1) Turn FUNCTION switch to +DCV.
(2) Short VOLTS terminal to COM terminal, and OHMS terminal to COM
terminal, using two leads (B2).
(3) Adjust DC ZERO/
control for zero indication on top scale.
(4) Turn FUNCTION switch to OHMS.
If meter does not indicate zero,
perform b below.
(5) Remove shorts connected in (2) above.
b. Adjustments. Adjust A1R5 REG ADJ (fig. 2) while turning FUNCTION switch
between OHMS and +DCV until meter indication is the same in both OHMS and +DCV
positions (R).
10. Dc Volts
a. Performance Check
(1) Connect calibrator to TI VOLTS and COM terminals.
(2) Turn TI FUNCTION switch to +DCV.
(3) Adjust calibrator output for an indication of 1 on TI meter 0 to 1 scale.
If
calibrator does not indicate between 0.098 and 0.102 volt, perform b (1) and (2) below.
(4) Repeat technique of (3) above at TI RANGE switch settings and meter
indications listed in table 3. Calibrator will indicate within limits specified.
