Performance Tests
b) Press
[Sensitivity Up/Dn]
Select the sensitivity from the table.
c) Wait for the R reading to stabilize. Record the value of R for each sensitivity.
4) Frequency response is checked at frequencies above 1 kHz. The test frequencies are listed below.
Test Frequencies
24 kHz
48 kHz
72 kHz
96 kHz
a) Set the AC calibrator to 1 kHz and an amplitude of 200.00 mVrms.
b) Set the frequency synthesizer to 1 kHz.
c) Press
[Sensitivity Up/Dn]
Set the sensitivity 200 mV.
d) Set the AC calibrator and frequency synthesizer to the frequency in the table.
e) Wait for the R reading to stabilize. Record the value of R.
f) Repeat steps 4d and 4e for all of the frequencies listed.
5) This completes the amplitude accuracy and frequency response test. Enter the results of this test in
the test record at the end of this section.
