5  Operation Thickness profiles with the B-scan
5-42 Edition 4 (05/2014) DMS Go+
5.12 Thickness profiles with the  
B-scan
Apart from the A-scan, the DMS Go+ presents another 
possibility of graphical evaluation: the B-scan. 
The B-scan enables you to display a thickness profile of 
the test object on the screen of the DMS Go+.
You can carry out measurements continuously over a 
maximum period of 30 seconds for the B-scan display 
with the values from these measurements being used 
by the DMS
 Go+ for displaying a subsection of the test 
object. For this purpose, guide the probe over the sec
-
tion to be displayed during the measurement period.
The display opposite shows the typical B-scan of a test 
object with a corroded backwall.
A valid zero calibration must be carried out 
for the display of the B-scan.
The display update rate is automatically in-
creased to 32 Hz during the measurements 
for the B-scan.
