Description of the parameters of the “MANUAL” mode:
– “AMP.”: amplification is adjusted automatically (AGC), or manually;
– “START”: the point of start of the selected gate (from 0 to the maximum measurement range);
– “WIDTH”: the width of the selected gate of the beam control. This value can vary from 0 to the
maximum measurement range. The total of start and width of the gate cannot exceed the maximum
measurement range;
– “THRESHOLD”: the threshold of the amplitude of processing of “THRESHOLD” echo signals.
The range is from 0 to 100%;
– “DUR.”: duration of scanning;
– “DELAY”: this parameter sets the delay of the start of scanning against the monitoring pulse;
– “LEVEL”: turn on/turn off;
– “AVG.”: turn on / turn off, and set the quantity;
– “GATE А/GATE В”: a selection of the gate. It can be А or В.
2.3.2.3 “В SCAN” mode
“В SCAN” mode (fig. 2.8) is used for displaying of В-Scan that is the shape of the test object.
This mode is used for detection of the corrosion damages, reduction, and lamination when scanning
the test object and graphical B-scan.
Figure 2.8 – “В SCAN” mode
All the settings of parameters of measurement in the “В SCAN” mode are divided into groups
(tab. 2.2).
