TsubO,
NI-DMM 2.2 installs with an example program for CVI that shows how to acquire data continuously with a NI DMM. The example is accessible through the START menu, and is installed by default in the folder: ...Program Files\National Instruments\CVI70\samples\niDMM\Multi Point\Cont Acq & Chart
You can learn about the programming flow of a continuous multi-point acquisition in the
NI Digital Multimeters Help, which also installs with the NI-DMM driver and its accesible through the START menu. Go to the "Programm
ing" section in the help file. I recommend you to look at the "NI-DMM Programming Flow" entry and the sections Single Point Acquisitions, Multiple Point Acquisitions and Continuous Acquisitions under the "Features >> Triggering" entry.
Hope this helps,
Claudia Lorente
