B‑SCAN LOS MODE
Determines how the B-scan behaves when a loss-of-signal (LOS) occurs.
STOP ON LOS
The B-scan stops scrolling when a LOS occurs. When the instrument regains
measurements, a thin blank vertical line is inserted into the B-scan as a
marker showing that a LOS has occurred (see Figure 10-6 on page 141).
CONTINUE ON LOS
The B-scan continues scrolling when a LOS occurs.
B‑SCAN FREEZE MODE
Determines which A-scan waveform and thickness reading are displayed when
you press [FREEZE] while a B-scan is active.
SHOW MINIMUM
Displays the waveform and thickness reading for the minimum reading
collected during the scan.
SHOW MAXIMUM
Displays the waveform and thickness reading for the maximum reading
collected during the scan.
SHOW CURRENT
Displays the last thickness reading made before pressing [FREEZE].
B‑SCAN FREEZE REVIEW
When this feature is enabled and a B-scan is active, pressing [FREEZE] freezes the
B-scan image in review mode. In this mode, a vertical line, the review marker,
appears to indicate the location of the displayed thickness (see Figure 10-7 on
page 143). The displayed thickness is either the minimum, maximum, or current
thickness depending on which B‑SCAN FREEZE MODE option is selected. The
38DL PLUS displays both the thickness value and the corresponding waveform.
Use the [] and [] keys to move the review marker and read the thickness at the
review marker location.
TIP
If the minimum or maximum value moves off the B-scan screen, press [FREEZE] to
center the B-scan and the review marker on the minimum or maximum thickness.
