Signal Quality Metrics

Build up on the probe and different surface conditions are factors that can affect signal and noise levels. Signal Quality Metrics can give an indication of how good the surface signal is compared to the noise. See Signal Quality Metrics page C-18 in Appendix C: Advanced Configuration.
