Terminology

It is a good initiative with the video presentations. However, "cut-off" is not a frequency as stated in the presentation. It is a length - as also indicated on the back of the instrument. So when it is stated in the presentation that you should have a high "cut-off frequency" for the rougher surfaces the meaning becomes the opposite, as a high cut off high frequency means a short cut off wavelength and vice versa.
