Is this possible?

Hello. 

I have a PXI-4070 mux'd with a PXI-2503. I am trying to create multiple VI's to read the DMM (for example, one VI for voltages on a range of channels, one for resisrtance on another range, etc). Is this possible? There appears to be only one IVI instrument handle for each PXI device and whenever a new VI is run it wipes out the VI that was already running.

Thanks.

The DMM can only be doing 1 thing at a time. If you want it to do multiple things, then you need an application/VI that your other applications/VIs can talk with. That lone VI does all of the interfacing with the DMM, acting as a mutex as needed.
