Hi,
I must read a voltage signal (0-16 V AC across the terminals), and I have the NI-9221 at hand (datasheet: http://www.ni.com/pdf/manuals/375905a_02.pdf). However, this can only read single-ended signals, and I need to measure across the two terminals. My question is, can I ground one terminal and plug the other into one of the channels and perform a normal single-ended measurement?
Best regards,
Fredrik
