Manual Mode Scanning Pattern - eddyfi R-Scan Array User Manual

11. Secure the encoder umbilical cable clip to the strain relief point on the scanner then connect
the encoder cable in the spiral wrap umbilical to the encoder umbilical socket by aligning the
white dots.
CAUTION
Ensure the encoder umbilical is attached to the strain relief point on the scanner handle.
Failure to do so could result in damage to the cable assembly.
12. Connect the water hose in the spiral wrap umbilical to the water box on the scanner.
CAUTION
Ensure that no undue strain can be put on the water hoses.
13. Connect the water hose to the pump.
14. Attach a tether to the handle of the scanner.
15. Using the Eddyfi PA UT instrument follow the onscreen setup instructions paying particular
attention to the following options:
a. In Specimen ensure the thickness value of the test item is entered correctly.
b. In Probe select the Silverwing PA G14 with the 15mm or 30mm water box wedge.
c. In Scanner select the Silverwing R-Scan Array.
i. Ensure Input coder is set to 3.
ii. Ensure Opposite Direction is ticked.
iii. Check the physical distance moved by the scanner is correctly displayed in the
Scan(mm) box in the software. If required perform an encoder calibration by
following the onscreen instructions.
d. In Settings seek guidance from technical authority for setup parameters.
e. In Configuration, motion, trajectory tab ensure the increment step value matches the
indexing distance of the scanner when moved perpendicular for the next scan.
f. In inspection press play to begin the data capture in the desired scanning pattern.

Manual mode scanning pattern

A 2-axis stitched C-Scan can be generated by scanning in either a uni-directional or bi-directional
scanning pattern.
Figure 8: Uni-directional scanning pattern
Uni-directional scanning steps using the R-Scan Array scanner:
1. Press play and move scanner forward to capture data for the first scan.
2. When the target distance has been reached, press the red pause/resume button to pause the
scan.
3. Slide scanner across perpendicular to next scan path then pull it backward to position it at the
start of the next scan.
4. Press the blue indexing button to increment the index axis position on the software ready for
