KG, I'll respond to both of your most recent posts here:
"Now it is clear even to me that the Edge-Lab tests cutting performance of the blade, not the sharpness at the edge apex as PT50."
That's about the size of it KG if we are talking about testing in SLC (Slice) mode. Of course both E LAB instruments are capable of taking edge sharpness tests just as the PT50 Series instruments do but with one added feature; the results of edge sharpness tests can be transmitted to a PC and saved in a file.
"Mike, do I read the E-LAB manual right, that it keeps in memory only data from the last test, and if we do not "send" it to the PC and save, the next test will overwrite the data?
If no, how many tests can it keep in the memory? - the specs do not mention it"
The E LAB manual is still a work in progress so I won't go back to it and then quote - I'll just tell you here how saving test data files works. When a computer has been connected to the E LAB instrument, the data collected from any one test is logged and stored at the PC - not in the instrument. At the conclusion of any test the user is given the option to save that data (and/or graph) to disc. Previously saved test data will not be overwritten or lost unless the user elects to delete the file that he/she previously created. The potential number of test files saved is only limited by the capacity of the user's hard drive. We must have really done a poor job of explaining this in the manual because I know that you understand computer functions as well we do.
"Also I cannot visualize how one can test slicing stuff other than the Slice Test Media, like the manila rope or cardboard - a demo video would be helpful."
And a very straight forward experiment it would be KG! Using our SLCP Slice Plate accessory, one would simply clamp (using the Slice Plate clamping system) a section of rope down to the Slice Plate and conduct the test. You could pull slice it, push slice it, or pull and push slice it within the same test and all the data will be there for you to examine. I demonstrated the Slice Plate accessory https://youtu.be/5euSsjmjpd0 in one of our E LAB videos by slicing a zucchini. Substitute the rope (or cardboard) for the zucchini and you're in business!
