(4) Adjust calibrator for an output of 1.9990 V.
(5) Adjust 2 F.S. (2VDC) (fig. 3) to obtain an indication of 1.9990 on TI.
17. Dc Current
a. Performance check
Connect TI COM and MA/K
terminals to calibrator current outputs.
(1)
Press TI M.A. function pushbutton and .2 range pushbutton.
(2)
(3) Adjust calibrator to obtain a 199.9 indication on TI. Calibrator will indicate
between 199.1 mA and 200.7 mA.
(4) Repeat technique of (2) and (3) above using settings and indications listed in

a. Performance Check
(1) Connect calibrator HI and LO outputs to TI.VOLT and COM terminals.
(2) Press TI A.C. function and 2 range pushbuttons.
(3) Adjust calibrator output frequency to 100 Hz and voltage to obtain an indication
of 1.999 on TI. If calibrator output does not indicate between 1.9790 V and 2.0190 V ac,
perform b (1) and b (2) below.
(4) Repeat technique of (2) and (3) above using settings and indications listed in
table 9. Ac voltage calibrator will indicate within limits specified.
