10.3 B-Scan
A B-scan is a cross-sectional image of thickness readings. The 38DL PLUS can acquire
and display B-scan data (see Figure 10-3 on page 139). When you activate the B-scan,
the thickness reading profile builds up and scrolls on the screen. Once a B-scan is
acquired, you can freeze the screen and review the recorded thickness values.

While the B-scan is running, you can save individual thickness readings, save the
current B-scan screen (with all thickness values), or the entire scan (up to
10000 readings) [see “Saving B-Scans, A-Scans, or Thickness Readings” on page 145].
You can activate and configure the B-scan from the B‑SCAN screen (see Figure 10-4
on page 140), accessible by pressing [SETUP MENU], and then selecting B‑SCAN in
the menu.
