Hi @Hyeontae-Song ,
I am not sure whether I got your question correctly. Are you asking whether Easergy P3 can be used to measure three voltage sources simultaneously?
Yes, it can with a little trick and very limited fashion. Only single phase measurement is possible then.
Can you elaborate your question, please.
