Unexpected results typically occur because of improper wiring or programming, electromagnetic
radiation, or damaged cables. Ensure that the data logger program includes the correct
parameters for the measurement instructions. Check for the presence of strong sources of
electromagnetic radiation and use the 50 or 60 Hz integration option in the data logger program
if electromagnetic radiation can be a problem. Check the cable for damage and ensure that it is
properly connected to the data logger.
