CTS Series - EN / IEC 61000-3-3 Flicker Test- Includes Amendment 1
Simple User Interface
The Flicker and harmonics test modes use similar , easy to use
interfaces. Setup is minimal and test runs can be started quickly.
During the test run, graphical displays of V
RMS
, d
c
and d
t
as a func-
tion of time are updated continuously. The left hand side of the
display shows both, instantaneous and peak-hold parameters for
the EUT such as V
RMS
, d
max
, d
c
,d
t
and instantaneous Pst. At the end
of the test sequence, short term (P
st
) and long term Flicker (P
lt
) are
calculated and a clear PASS or FAIL indication is provided.
Available Data Displays
The following graphics displays are provided in the IEC 61000-3-3
test program:

Test Reports and Data Logging
A Flicker test report can be printed at the end of the test in MS
WordorOpenOceformat.Thisreportincludesallickertest
results for the EUT. If the test was selected, inrush current and d
max
measurement results are included in the report. A sample report
is shown on the opposite page.

Highest values found
during test are continu-
ously shown and up-
dated every second.
Clear Pass (Green) or

IEC Flicker Test Window
The CTS system also records comprehensive test data records on
disk for use in detailed reporting or further data analysis applica-
tions. Flicker data is stored in both compact binary and ASCII format
les. The latter format can be loaded directly in popular spread-
sheet programs. A test le replay mode is supported by the CTS
system software that allows frame by frame playback of test data
les for detailed analysis of EUT behavior. This replay capability also
allows the CTS owner to submit test data to California Instruments
for review so he can benet from the experience of our technical
sta when interpreting test results.
