NOTE
If necessary, repeat 7 g through i above.
(24) Connect RF probe to calibrator WIDEBAND OUTPUT.
(25) Adjust calibrator for 3 mV ac output and then adjust R6 (fig. 1) for a TI
indication between .0027 and .0033 V ac (ideal .003 V ac) (R).
(26) Set RANGE switch to .1-VOLTS. Adjust calibrator for .10 V ac output and then
adjust R19 (fig. 1) for a TI indication between .09 and 0.11 V ac (ideal .1 V ac) (R).
(27) Set RANGE switch to .3 VOLTS. Adjust calibrator for .3 V ac output and then
adjust R21 (fig. 1) for a TI indication between .27 and .33 V ac (ideal .3 V ac) (R).
(28) Set RANGE switch to .01 VOLTS. Adjust calibrator for .01 V ac output and
then adjust R10 (fig. 1) for a TI indication between .009 and .011 V ac (ideal .01 V ac) (R).
(29) Set RANGE switch to .03 VOLTS. Adjust calibrator for .03 V ac output and
then adjust R14 (fig. 1) for a TI indication between .027 and .033 V ac (ideal .030 V ac) (R).
(30) Set RANGE switch to 1 VOLTS. Adjust calibrator for 1 V ac output and then
adjust R23 (fig. 1) for a TI indication between .9 and 1.1 V ac (ideal 1.0 V ac) (R).
(31) Set RANGE switch to 3 VOLTS. Adjust calibrator for 3.0 V ac output and then
adjust R25 (fig. 1) for a TI indication between 2.7 and 3.3 V ac (ideal 3.00 V ac) (R).

R F probe using 50 feed through termination supplied with TI.
(2) Set RANGE-FULL SCALE SWITCH to .1 VOLTS.
(4) Adjust calibrator output voltage controls for .1 V indication on TI meter.
Calibrator voltage output will be within the limits specified in table 4.
