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. When searching for larger objects such as
delaminations or thickness variations, much coarser grid spacings may
be used, e. g. 10 cm and upwards.

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.
If one contact pair fails the test, it may
be repeated before continuing.
Units
Choose between metric and imperial units
Echo Tracking
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.
Filter
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.
• Normal – Applies a medium band filter to the received signal.
The received signal is saved post-filtering, so it is not possible to alter the
filter afterwards. Switching the filter off allows the raw data to be viewed.
Time Gain Compensation
When switched on amplifies signals that are further away from the trans-
ducer.
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.
Color Range and Color Scheme
Color range may be automatic or manual. When set to manual, the color
gain icon 9 appears on the measurement screen.
Four different color schemes may be chosen according to preference.
