Hi everyone.
I have to sort a batch of J201 bought years ago. Building a Fetzer Valve from RunOffGroove, I need Idss and Vp to use their calculator.
http://www.runoffgroove.com/fetzervalve.html#12Since I had useful results when dealing with "classic" BJTs with my cheap MK-328 tester, I thought it might be of some help to speed up the process.

This is what the device displays for a J201 as DUT. Looks fine, but I get a bit confused with the results. What this means ? The tester documentation is pretty thin and didn't gave me much information.

So if you guys have any clue on this or using this tester on JFETs, it would be much appreciated, thanks in advance :)
