    I have an issue with unwanted voltage. I am working on a program with Labview and I need a little assistance. I have some voltage on the input of my DAQ card that I need to get rid of. It is approximately .125 volts. I constructed a filter thinking it may have been noise but the voltage is still there. Is there any way to get rid of this voltage? I need to get rid of the excess voltage in order for my RPM meter in the program to read accurately. Any ideas?

    Not without seeing the schematic.

    Please post it in .png format; that format is compact and not "lossy" like .jpg or other types.

    Short the input to ground.
