Hey Trinity79,
This seems pretty odd, and I've never heard of it. I would suggest an uninstall and upgrade of both your NI-DAQ and DMM. The current versions of these are (NI-DAQ) 7.4 and (NI-DMM) 2.3.1. There have been several "minor" issues with new 4070s and older drivers, so I would suggest an upgrade as a first defense. Let me know what happens.
Sincerely,
Gavin Goodrich
