(9) Set signal generator for 1 kHz FM deviation and a modulation rate of 100 Hz.
Adjust the amount of deviation until measuring receiver indicates 1.000 kHz FM and press
FM Z (F3). Wait for zeroing process to complete.
(10) Algebraically subtract + residual FM recorded in (8) above from TI DEV
indication and if result is not within limits specified in table 21, perform b below.
