Why is the voltage reading in the History plot less/more than the true signal voltage?
BioSigRP requires the user to set the gain setting in the acquisition setup (unless you are using the DB4 bioamp). If you changed the gain setting on your amplifier and did not also change it in the Setup Channels dialog box then the voltage readings might be off. Go into the Setup Channels dialog box in the acquisition dialog box to modify the gain setting.
