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.

F2 (strobe)

The strobe is used to set control zones, levels of susceptibility and Automatic Defect

Signaling actuation, measurement of defect coordinates and signal amplitudes from reflectors in

an interval of interest

If the signal exceeds the strobe level, the cursor is automatically set at the point where

exceeding has occurred (or at the maximum), the corresponding parameters of the cursor in this

point are displayed, and sound and light indication occurs (Automatic Defect Signaling

actuation).

If the strobe is located outside of the displayed diapason, a pointer appears near the right

border of the diapason, which allows determining the level of the strobe threshold (a single red

arrow).
