Note.
The flaw detector has a feature, which allows the quick signal/noise ratio
measurement. In order to measure the ratio, first place the measuring cursor on defect free-area
in the strip chart and press
– defect free area "F1 An" key, then move the centre of
measuring cursor to the signal peak from a defect. The result appears in the right bottom corner
of the flaw detector electronic unit at the "К= …" position, the measured signal/noise ratio will be
displayed.
In the view menu it is possible to estimate the saved or just taken data; carry out the
assessment of detected defects depth. By changing the position of measuring cursor, change
the cursor width in such way that the signal from defect stays within the cursor width. In this
case, the amplitude “A: ”, phase “P: ” and estimated defect size in millimetres or percent “D: ”
will be displayed in the flaw detector bottom information bar; the path data in mm will be
displayed in the top panel during the testing with ENC. By moving the cursor to the next signal
from defect, the data corresponding to the marked defect will be displayed on the screen.
The depth of the defect will be displayed only if the correct calibration curve is created!

“Memory” Menu
In order to load/save testing results or device settings, it is necessary to press
- key,
choose submenu "RESULTS" or "SETTINGS" and press
key. The flaw detector is capable
of storing of more than 1000 settings and up to 1000 testing results (depending on the
defectogram size) in the memory.
