Do not understand RMS voltage

Hello

I have to write a measurement software that uses a NOR-DAQ 6071E. C++ is used as programming language and the new DAQmx interface is used and seems very well at the moment.

Now, I have a few Questions about the two functions

DAQmxCreateAIVoltageChan

DAQmxCreateAIVoltageRMSChan

The first give me the unmodified sampled values?

The second makes some calculation on each sample?

I need to create the average arithmetic and the RMS of the samples. These features help me with that. Or do I have to do the calculations on my own?

I know I have to do the calculations on mine, which is not a problem.

Would be great for some advise

BR

Hi Hans-Jürgen,

The DAQmxCreateAIVoltageRMSChan() function is only supported for the integrated DMM to the NI ELVIS II and NI ELVIS II +. For the OR 6071E, you need to use DAQmxCreateAIVoltageChan() and do the calculations yourself.
