61000-3-2: Test Flow
The test flow is shown below. The test execution is from when the START key is pressed, and
until when the test time expires. After the end of the test time, you can save the test results,
print reports, terminate the test and analyze the test results.

For details on analyzing the test results and judging conformance to the standard and AC
power supply and repeatability checking, see Chapter 7
“ Observation, Analysis and
Judgement of Harmonics .”
