L/D ratio

When doing a coil shot, if you are using a Gauss meter or QQI to verify your amperage, do you still have to have a L/D ratio minimum of 2?

Re: L/D ratio
In Reply to mike lassman at 19:11 Oct-01-2015 (Opening).

Low L/D ratios make both attaining required levels of magnetic flux in the component and proper demagnetisation difficult.

Can you use extenders to increase L/D ratio?

...
oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
