a. Performance Check
(1) Set NORMAL-REVERSE switch to NORMAL and INT-EXT to EXT.
(2) Short INPUT EMF and EXT GALVO terminals.
(3) Connect digital multimeter/multimeter to TI EXT VOLTMETER terminals.
(4) Adjust REFERENCE EMF COURSE, MED, and FINE controls for an
indication of 5 on TI EMF DC meter. If digital multimeter/multimeter does not indicate
between 0.49625 and 0.50375 V dc, perform b below.
(5) Repeat technique of (4) above at TI meter indications listed in table 10. Digital
multimeter/multimeter will indicate within limits specified.
(6) Remove installed short.

b. Adjustments
(1) Adjust TI REFERENCE controls until digital multimeter/multimeter indicates
0.50000 V.
(2) Adjust R13 (fig. 8) until TI EMF DC meter indicates 5 (R).
(3) Repeat a (4) and (5) above, and if required, b (1) and (2) above for best in-
tolerance compromise.
