Hi,
I am using NI 9237 datalogger and labview signal express 3.0. I measured strain using full bridge configuration. the data recorded was for strain corresponding to every 0.00062 second and i am getting a huge data. I want to measure strain data for one second, i changed sampling rate but it was of no use. Could anyone tell me how to change sampling rate to 1Hz in NI 9237.

The 9237 has a minimum sample rate of 1.613kS/s. Sampling any lower will default to its closest valid sample rate.
Page 20 on the manual explains the different (available) sampling modes.

Thanks for your help
I am new to signal lab view signalexpress. yes the manual states a minimum sampling rate of 1.613 kS/s. Does that mean i can't change sampling rate to 1Hz.

You can lower the sample rate by adding an additional Subset and Resample step.
Read through this post and see if that gets you to where you need to be

Hi,
I couldn't open the attached file as it is in labview signal express 2009 and I am using version 3. so could you help me with subset and resample step setting
