NI-Dmm: Difference between fetch and read?

Solved!
Go to solution

I'm working with the Ni-Dmm .net library, interacting with a PXI-4065 DMM.

 

What's the differnce betwen NIDmm.Measurement.Fetch() and NIDmm.Measurement.Read()?  And associated fetch/ read functions (eg: MemoryOptimizedFetchMultiPoint() vs MemoryOptimizedReadMultiPoint())?  

 

I would read the documentation, but all of the API references don't contain any information.  The API pages are blank.

 

EDIT:  Documentation is there...I just can't read the destructions..... 😐

The Acquiring Data section of the NI-DMM Help manual should be of assistance: http://zone.ni.com/reference/en-XX/help/370384N-01/dmm/flow_acquire/ The basic state model is: Initialize -> Configure -> Initiate -> Fetch -> Abort -> Close Read combines Initiate, Fetch, and Abort into one driver call. If performing multiple driver acquisition calls, Fetch is going to be faster than Read because it doesn't need to perform the Initiate and Abort state changes each time.
