Note: Harmonic currents less than 0.6% of the input current measured under the
test conditions, or less than 5mA, whichever is greater, are disregarded.
6.5 OPERATING CONDITIONS OF THE EUT
1. Setup the EUT and Test Equipment as shown on 6.3.
2. Power on the EUT. Acting performance checking program to allow EUT executing its usual
operation mode during test.
6.6 TEST PROCEDURE
Power Line Harmonics:
The EUT was supplied in series with power analyzer from a power source having the same
nominal voltage and frequency as the rated supply voltage of the equipment under test. The
supply voltage of the EUT was varied over the voltage range of 0.94 times to 1.06 times the
nominal voltage to produce worst-case emission.
6.7 TEST RESULT
1. The measurement of the power harmonics, which test at the extremes of EUT‘s supply
range was investigated, and the test result are reported the following data pages.
The measurement limits were met, and the EUT
passed
the test.
2. The EUT was complying to limit of Class D.
