B-Scan

The B-scan feature allows you to collect a single value B-scan from measurements
made in the Corrosion Module. A single value B-scan represents the side profile of a
test material based on thickness or time-of-flight (TOF) measurement. This view,
typically used in corrosion scanning applications, is used to verify acquired thickness
measurements, and also to provide a visual reference showing areas on the part with
critical thickness values.
