Is there any filters for Ni9237

[JohanSalomonsson]

Hi

Is there any way to filter a signal from a NI 9237 that are used for measure a loadcell.

My settings are.

SampleRate = 10000;

SamplesPerChannel = 1000; 

The channel is set up as a StrainGageChannel

I get at signal that have a diff off -+50 gram and does not look good. see attached png-file

I'm trying to measure a signal that I do a fft on and try to determine a frequency of 100 Hz

Is there any filter that I can add to get a cleaner signal?

Hi Johan, 

Have you seen the article Wiring considerations for the NI 9237 module?

Please can you check you are using a NI 9949 and that you have wired it up correctly for your bridge configuration which is set in NI-MAX. Full wiring diagrams can be found from page 12 of the Getting Started Guide. This is mostly to be the source of the noise on the signal. 

I hope that helps!
