Our do I check Ford spark plug wires?

[Lonesome7.3]

I have already gotten a little bit of help on this and I have watched a bunch of videos on the subject. However, the more I watch the more confused I get. Our 96 F250 with a 351 gasser runs real rough. I have a suspicion a plug wire(s) is bad. I have a new multimeter but I do not know how to use it. That is one of the problems I am facing. All the videos I have seen use different meters. Where do I set mine? When I do get it set correctly, what numbers do I want to see when testing the wires. Please feel free to break this down to dummy level and a step by step would be nice as well.

And this is the meter I have:

Are spark plug wires supposed to have resistance? I just assume it was a wire that offered little to no resistance. If so you just need to check for continuity. Mine has a setting that will beep if tere is no interruption in the circuit. Or you could use the ohm setting. Looks like an upside down "U" or horseshoe. With no resistance it should read zero of very close. .

I think resistance is what I am suppose to be looking for.

I realize this is for a Mazda but it is plug wires so maybe it will give you a ballpark idea of what to look for

Thanks, that did offer some different information.

Okay, here are the results.
I set the meter to 20K.
Number four at 29 inches was 11.69
Number three at 20 inches was 6.35
Number two at 18 inches was 6.09
Number one at 28 inches was 9.07
Number eight at 31 inches was 8.91
Number seven at 21 inches was 12.43
Number 6 at 17 inches was 6.37
Number five at 21 inches was 6.94
Coil wire at 21 inches was 7.12
As the manual said to do, I tested them through the cap.
