DMM (PXI-4065) sample multipoint

[gstemp]

If my PXI-4065 is executing a niDMM_ReadMultiPoint call, is it possible to call niDMM_Read (or some other function) from another thread and get the latest value read by the DMM while the ReadMultiPoint is executing?  It seems if I call niDMM_Read from another thread, it waits until the ReadMultiPoint completes before it executes.

Hi gstemp,

Thank you for posting on the forums.  Unfortunately you will not be able to perform these reads and the same time, the 4065 only has 1 Analog to Digital converter so you can't make 2 measurements at the same time.  You could either do a multipoint read and take lesss points so it updates faster or take a single point read and use and loop to continously aquire the data.  I know that this is not ideal for your situation but what you are trying to do is not actually possible with a DMM.  

I hope that helps,

Regards,
