Performance Tests
3) For each of the amplitudes listed below, perform steps 3a through 3c.
AC Calibrator Amplitudes
1.0000 Vrms
100.00 mVrms
10.000 mVrms
4.000 mVrms
a) Set the AC calibrator to the amplitude in the table.
b) Press the keys in the following sequence:
<Expand>
Highlight the R expand.
Enter the R Output Expand from the table.
c) Wait for the R reading to stabilize. Record the value of R.
4) This completes the amplitude linearity test. Enter the results of this test in the test record at the end of
this section.
