B-Scan (TKG150 only)
The B-Scan represents a cross sectional view on the test
piece. The simplest example is to show a 5 step test
block. To turn on the B-Scan on the TKG150, press
MENU/OK, scroll to MEASUREMENTS and press
OK, select B-scan and press MENU/OK. First enter the
maximum thickness you expect to scan using the up,
down, left and right keys, then turn on the B-Scan
scrolling down and right arrow (left arrow for off). Press
F3 in lefty or F1 in righty mode when done. The bottom
of the display will read SAVE, START or STOP and
CLEAR. To Start a B-Scan, couple to a
test block
and
press F2 [START]. If you uncouple the transducer, B-
Scan will stop due to LOS. If you press F2 [STOP] the
minimum thickness will be displayed in the center of the
screen while a vertical cursor allows you to review
readings. During review the thickness value is updated in
the top right of the display. To save all the readings, press
F1 [SAVE]. The amount of saved readings up to the file
size of 5,000 readings or what was pre-determined in the
current file (See Datalogging) set up. Here is a picture of
the B-Scan on a test block.
