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?
