The expectation once tests are complete is to undertake marketing throughout this year (2015). n Paper courtesy of the 63 rd International Wire and Cable Symposium, Providence, Rhode Island, USA, 10 th to 12 th November 2014 .

Still in laboratory conditions, a stainless steel wire 0.38mm in diameter (15mils) was moved and this generated marks or scratches.

In both cases the blue line determines the periphery of the defect. Unfortunately the display is cut right on the top of the wire where the marks are. ▲ ▲ Figure 7 : First case, one side inked mark. Reading at 25kHz

Nevertheless, it shows the computing analysis that works all around the wire. The surface quality of the wire can also be seen. Image calibration must be made on a smooth surface of the wires. This is also a process to develop to be able to deliver the reference wires. The measurements are not sensitive to the vibration of the wire. Nevertheless, the independency has to be optimised to the position of the wire. Conclusions This unique instrument is in its last optimisation phase. All technological issues are solved efficiently. ▲ ▲ Figure 8 : Second case, one scratch on the surface. Reading at 140kHz
