Position “Position” – moves the measurement cursor in the time chart.
Position “Width” – sets the width of the measuring cursor.
Position “Type” – the type of cursor measurement. Four types of
measurement are available.
° Pk-Pk – the measurements are made between two points situated at the
max. distance from each other in cursor width.
° Cnt-Pk - the measurements are made between the cursor center and the
point situated at the max. distance from the center in cursor width.
° Cnt-K - the measurements are made between the center and the cross
point of cursor center signal.
° Vrt-M – vertical maximum - the measurements are made between two
points situated at the max. distance from each other in the cursor width in
vertical projection.
Position “Measurer” – is intended for meter signal parameters displaying
in complex plane.
Position “Scan” – is for changing the number of points in a strip chart.
When moving the cursor in the strip chart, the complex plane display is
updated with the signal, which is located within the cursor width. The values
of amplitude in volts, phase in degrees and defect depth in millimeters or
percent are displayed in the information line.
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

key, then move the center 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

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 millimeters 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 (see Figure 19). By
