And that’s the thing. It’s horses for courses.
Following the sales pitch above for Kewtech, which I don’t disagree with, here is my counter pitch;
For ease of use and price IMHO you can’t beat a megger 15xx. Plug two leads in and leave them there. All tests on one dial. RCD selection on other dial. No menus, sub menus, function keys. Instant continuity tests. Run IR tests as long as you want.
They are incredibly robust and the batteries last forever. I genuinely believe it’s the simplest and easiest to use MFT there has ever been and probably ever will be.
(I agree that Kewtech testers are very easy to understand and use, and also a decent choice. I used to have one and passed my 2391 with one.)
