Question about Averaged DC-RMS for N Chans

hi,all
I am using Averaged DC-RMS.vi to filter random noise from waveforms. When
I input only one channel waveform, it works ok. like follow:

But when I input two channel waveforms, no waveform output. It should be
work according to the manual of Averaged DC-RMS.vi. as follow:

Any suggestion would be appreciate!!

There is an unfortunate bug in your version of the N-Channels DC-RMS VI. Try to use the attached VI instead.

We appologize for the inconvenience.

I just realized that you are using LabVIEW 7.0, while the fix I sent you is for LabVIEW 6.1.

So to fix your problem replace the library madcrms.llb located in your *\National Instruments\LabVIEW 7.0\vi.lib\measure\ folder with the one attached to this comment.

I am having a similar problem with the Basic Averaged DC-RMS.vi. I was hoping there is also a fix for this. I am using labview 6.1 and if possible i would like a way so that labview will point to the fix in the vi menus insted of me trying to remember that i need to use a different vi then the one listed.
Thanks for you time
Dave

You are, of course, correct on that approach. The first suggested fix for LabVIEW 6.1 was more a quick&dirty "Saturday" solution.

The official way is, as for 7.0 to replace the madcrms.llb libray in your *\Program Files\National Instruments\LabVIEW 6.1\vi.lib\measure\ folder with the one attached here.

Hi
I`m having a problem. I`ve been triying to plot diferent signals in matlab which has and hasn´t averaged dc-rms in my program of acquisition data in LabView 7.1, but i can´t see them because they have diferent size in their data and i need to compare each other with and without  averaged  dc-rms running in the same task. I`ll apreciate your help.
