- restoring the initial scale horizontally.
Scale (V) -
allows to adjust a vertical scaling of a signal image:
- scaling-up the signal image vertically;
- scaling down the signal image vertically;
- restoring the initial scale vertically.
Signal parameters located in a measuring cursor are displayed in information area of a bottom
status bar:
− Amplitude (V);
− Phase (deg.);
− D (mm) - conditional defect depth;
− Аn (dB) - noise amplitude;
− S/N – measured value of signal to noise ratio.
Note
– In order to measure the
S/N
ratio, place the measuring cursor on defect free-area
and press "An" key, then move the measuring cursor to the signal peak from the defect. The
measured signal/noise ratio will be displayed in the amplitude area.

Working with the program
4.14.3.1
Connecting the flaw detector to PC
Connect the flaw detector to PC using the USB connecting cable that is included to the flaw
detector delivery set.
Switch on the flaw detector by pressing the power On / Off
button and hold it pressed until
a short beep sound is emitted.
Wait until the flaw detector is recognized on PC as a removable media (when the flaw detector
is recognized as a removable media, it is displayed on PC screen).
4.14.3.2
Saving the testing results from the flaw detector memory to PC
To save the testing results from the flaw detector memory to PC, connect the flaw detector to
PC using a USB cable (item 4.14.3.1). In the menu of «PCE-USC 30» program select the item
"Loading"
, and after, in the program window there are displayed the files of all the testing
results stored in the flaw detector memory. Then, the program window asks to select the files
that can be automatically copied to the selected location on the hard disk drive of PC.
