NOTE

Ensure RF probe is connected to calibrator WIDEBAND

OUTPUT before proceeding to (23) below.

(23) Set RANGE-FULL-SCALE switch to 1-VOLTS. Adjust calibrator for 0.3 V ac

output at 300 kHz and then adjust adjustment number 1 for TI meter indication between

0.25 and 0.35 (ideal 0.3 V ac).

(24) Set RANGE-FULL-SCALE switch to 3-VOLTS. Adjust calibrator for 2.5 V ac

output and then adjust adjustment number 2 for a TI indication between 2.35 and 2.65 V ac

(ideal 2.5 V ac) (R).

(25) Set RANGE-FULL-SCALE switch to 1-VOLTS. Adjust calibrator for 0.9 V ac

output at 300 kHz and then adjust adjustment number 3 for TI meter indication between

0.85 and 0.95 (ideal 0.9 V ac).

(26) Set RANGE-FULL-SCALE switch to .3-VOLTS. Adjust calibrator for 0.28 V

ac output and then adjust adjustment number 4 for a TI indication between 0.265 and 0.295 V

ac (ideal 0.28 V ac) (R).

(27) Set RANGE-FULL-SCALE switch to .1-VOLTS. Adjust calibrator for 0.03 V ac

output and then adjust adjustment number 5 for a TI indication between 0.025 and 0.035 V ac

(ideal 0.03 V ac) (R).

(28) Adjust calibrator for 0.09 V ac output and then adjust adjustment number 6 for

a TI indication between 0.085 and 0.095 V ac (ideal 0.009 V ac) (R).

NOTE

Adjustment numbers 7 through 9 are located from rear to front

on left side of TI cabinet.

(29) Set RANGE-FULL-SCALE switch to .03-VOLTS. Adjust calibrator for 0.028 V

ac output and then adjust adjustment number 7 for a TI indication between0.0265 and 0.00295

V ac (ideal 0.028 V ac) (R).

(30) Set RANGE-FULL-SCALE switch to .01-VOLTS. Adjust calibrator for 0.009 V

ac output and then adjust adjustment number 8 for a TI indication between 0.0085 and

0.0095 V ac (ideal 0.009 V ac) (R).

(31) Set RANGE-FULL-SCALE switch to .003-VOLTS. Adjust calibrator for

0.0028 V ac output and then adjust adjustment number 9 for a TI indication between

0.00265 and 0.00295 V ac (ideal 0.0028 V ac) (R).

(32) Set RANGE-FULL-SCALE switch to .001-VOLTS. Adjust calibrator for

0.0009 V ac output and then adjust adjustment number 10 for a TI indication between

0.0008 and 0.001 V ac (ideal .0009 V ac) (R).

(33) Disconnect RF probe from calibrator.
