(8) Vary function/arbitrary generator frequency, from 100 Hz to 50 kHz while
maintaining indication recorded in (7) above. Function/arbitrary generator will indicate
between 8.9 and 9.1 V.
(9) Set GAIN switch to 20 dB.
(10) Repeat (7) and (8) above.
(12) Substitute true rms voltmeter for multimeter.
from 10 Hz to 1 MHz. If true rms voltmeter does not indicate between 7.2 and 10.8 V,
perform b below.
(14) Set GAIN switch to 40 dB and repeat (13) above. If out-of-tolerance conditions
exist, set GAIN switch to 20 dB and perform b below.
b. Adjustments
