Ive recently experienced some problems finding kneepoints using the CPC100. Last week i tested 60 CTs of various description and 57 of them were proven to be OK. The remaining 3 did some funny things with their saturation curve. They basically plotted a 45 degree line with a linear relationship between V and I. I tried everything and tested them 5 or 6 times with the same result. The next day i retested them and they worked fine. Nothing had changed. Initially i thought of magnetisation of the core but the way the test set works virtually rules this out.Has anyone seen this behaviour before? Is their a known issue with the test set?Am i missing something?

Also does anyone know where i can find information on customizing reports generated from CPC Explorer.

Thanks for you help
