3.2 A-SCAN mode (Echo method)
To set the control zone, susceptibility level, Automatic Defect Signaling actuation and
measurement of defect coordinates and signal amplitudes from reflectors in the intervals of
interest, a strobe is used in the device.
Measurement can be carried out in an automatic as well as manual modes.
Automatic mode is measurement mode when the strobe is on. The value of the point
amplitude exceeding the strobe level, depending on the set actuation manner, is measured. If an
echo signal gets in a time span of the strobe and signal amplitude exceeds the strobe level, the
cursor is automatically positioned at the place of actuation and indication of measured
parameters. In addition, the fact of exceeding of the strobe level by the signal is accompanied
with a sound signal and switching on of the corresponding red LED indicator on the front panel
of the device. If the signal is below the strobe, its fixation and measurement are not conducted.
Manual mode is measurement mode when the strobe is off. The signal is measured by
means of the cursor movement with the help of the buttons.
Besides the cursor, the marker in a form of a colored triangle is displayed, which is always
automatically set at the maximal value of the signal amplitude within the strobe.
