7 Adjust the output so that the multimeter reading displays the first Volts/div
precision source setting value in Table 8 or Table 9 (depending on the
oscilloscope model).
8 Disconnect the multimeter.
9 Wait until the measurement settles.
10 Read the “current” average voltage value again as V2.
11 Calculate the difference V2 - V1.
The difference in average voltage readings should be within the test limits of
Table 8 or Table 9 (depending on the oscilloscope model).
If a result is not within the test limits, go to the “Troubleshooting” chapter. Then
return here.
12 Disconnect the precision source from the oscilloscope.
13 Repeat this procedure to check the DC vertical gain accuracy with the
remaining Volts/div setting values in Table 8 or Table 9 (depending on the
oscilloscope model).
14 Finally, repeat this procedure for the remaining channels to be tested.
