A successful test is indicated by the
transducer pair being highlighted green.
The next pair to be tested is then high-
lighted blue.
Continue until each transducer pair has
been tested.
B-Scan
Distance between measurements
Set the spacing between measurements. For good resolution images,
a spacing of 1 cm is recommended. For a quicker initial scan a coarser
spacing may be used, e.g. 2.5 cm corresponding to the spacing markers
on the Pulse Echo Transducer.
2.5 cm
Units
Choose between metric and imperial units
Echo Tracking
When Echo Tracking is activated, the main echo is highlighted white in
the A-Scan on the measurement screen.
This is particularly useful if a quick read-out of slab thickness is desired.
For complex objects containing internal defects, pipes and rebars it is
recommended to perform a complete B-Scan for analysis of the object.
Filters
Filters are used to filter out unwanted noise, to make it easier to identify
the correct echo.
• OFF – No filter is applied. The raw signal is displayed.
• Narrow – Applies a narrow band filter to the received signal.
• Normal – Applies a medium band filter to the received signal.
• Wide – Applies a wide band filter to the received signal.
The received signal is saved post-filtering, so it is not possible to alter the
filter afterwards. It is best to experiment to find the optimum filter setting
before carrying out the complete B-Scan.
Envelope
When this setting is activated it uses an envelope of the A-Scan to gener-
ate the B-Scan image. This can also help to generate a clearer B-Scan
image.
