5.5 Running a Harmonics Test
Starting the CTS 3.0 main program brings up the test setup screen. This CTS 3.0 main program
window automatically sizes to a SVGA display resolution of 800 x 600 pixels. Larger screen
resolutions are supported but the controls on the main window will not size to any resolution above
800 x 600.
For correct harmonics and flicker measurement operation, please note the following setup
guidelines:
1. Make sure that the PACS and PC are operated from the same supply line.
2. Make sure that the power source is operated from the same basic supply circuit as the
PC and PACS unit.
A harmonics test is always started by setting the desired type and EUT class. Other settings
involve the desired nominal voltage and frequency and test window size. The figure below shows
the typical settings for a class A test.
Please note the six fields at the bottom of the set up screen are grouped as Default user input.
The values you entered in these fields are not necessarily for the particular test you are about to
perform. When you click OK, you will be presented with a measurement screen where you can
enter similar information that is specific for the test. The Default User Input here is intended to
facilitate the situations where a group of tests are to be performed where the information in
Default User Input are applicable to all the tests in the group.
