levels were recorded for reference of the final test.
Procedure of Final Test
EUT and support equipment were set up on the test bench as per the configuration with
highest emission level in the preliminary test. A scan was taken on both power lines,
recording at least the six highest emissions. Emission frequency and amplitude were recorded
into a computer in which correction factors were used to calculate the emission level and
compare reading to the applicable limit. The test data of the worst-case condition(s) was
recorded.

The EUT was placed on the top of a wooden table 0.8 meters above the ground and operated
to produce the most unfavorable sequence of voltage changes under normal operating
conditions.
to produce the most unfavorable sequence of voltage changes under normal operating

During the flick measurement, the measure time shall include that part of whole operation
cycle in which the EUT produce the most unfavorable sequence of voltage changes. The
observation period for short-term flicker indicator is 10 minutes and the observation period
for long-term flicker indicator is 2 hours.
