(23) Calculate source flatness in table 6 below by subtracting 1000 Hz recorded REF
Difference % = value recorded in table -
Hz recorded REF table
from listed frequency value recorded in table 5 above, as shown below:
(24) Calculated source flatness (mV), must be within corresponding limits specified
in table 6 below.
(25) Repeat technique of (23) and (24) above for remaining parameters and limits
listed in table 6 below.

b. Adjustments
(1) Remove top cover of TI; A2 board is located towards front of TI.
(2) Press TI numerical key for 41.0 and then SPCL key to initialize TI. Set INPUT
switch to ground. Set LP FILTER off. Key in 1.10 SPCL to set input to 4.76 V range.
(3) Set CALIBRATOR for 4.5 V rms at 1 kHz and connect CALIBRATOR to TI
HIGH INPUT.
