remove fuse physically from the circuit and test with a meter - not just one leg of the fuse but both legs... be careful, some fuses will set off the alarm, and it is loud and obnoxious...
never trust a visual inspection of a fuse, as there might be a hair crack in the fuse, preventing flow of juice but visually looking good...
i suspect that the thing that you have is testing for "presence" of electricity in the circuitry but again, i do not use those fancy things, they are too smart for old crusty me... lol...

Thanks so much! Now I know what not to do lol I'll do that from now on! So I test them off the circuit with a tester that makes contact with both probes! Got it! And ALL of them have to make a light turn on to indicate they are good? Correct
