Figure 2. Frequency response.
(2) Set TI DB dials to 0.
(3) Adjust calibrator for a 0.3162 volt, 1 kHz output.
(4) Record true rms voltmeter indication.
(5) Set TI 0 to 10 DB dial to 1.
(6) Adjust calibrator output until true rms voltmeter indicates value recorded in (4)
above. Calibrator will indicate between 0.3527 and 0.3569 V ac.
(7) Repeat steps (5) and (6) above for remaining dial settings at 1 kHz, listed in
table 4 below. Calibrator will indicate within limits specified.
(8) Set calibrator output to minimum; then set TI dials to 0.
(9) Repeat technique of (3) through (8) above for 100 kHz, 1.0 MHz, 20 kHz and
30 kHz as listed in table 4.
b. Adjustments. No adjustments can be made.
