Hello

We have a Harmonics and Flicker rack which consists of a Voltech PM6000, Voltech IEC Standard 555 Reference impedance, and a Pacific 140-AMX Programmable power Source. The rack is using IEC61000-3 for PM6000 Release 1.25.12 Software.

When the run a test and print out the Source Qualification result, it gives an overall result of PASS but the printout shows that the Crest Factor fails. Is this a problem with the power supply or is it in relation to the unit under test.

Please see attached results.

Hi Bob,

I think that this failure should be causing the overall result to fail, but the crest factor failing is very unusual so it hasn't been spotted before. It is possible that the value is wrong due to the level of firmware that you are using in the PM6000. Please download and install the latest version of the firmware from here: http://www.voltech.com/Support/Forum/tabid/151/forumid/3/threadid/1517/scope/posts/Default.aspx.

Please try the upgrade and let me know how you get on with it.

Best regards,

Tim.
