Voltage drop

[Don]

I was a bit surprised myself. 

And a bit burnt as my hands kept slipping on the probes and getting uncomfortably close to the coils. I think I'll go back to using the Fluke, the meter I was using took a second or more to give a reading which is not helpful in a hot object whose resistance rises rather a lot with temperature. Which will again influence volt drop. I thought the extra digit might be useful, but the extra slowness is not useful

The Igo-M would be pretty useful for those tests. You could clamps the meter probes in as if they were a second coil perhaps ?

[Don]

That's a plan. I really do need some sort of test rig to hold the leads in place. I suspect it'd be a pig to solder to or I'd just solder a lead to the + post and the deck. Stick 4mm plugs on it and the job's done. Come to think of it, I have a spare dripper or two. Easy enough to wind one to any desired resistance if the top cap doesn't have to go back on.

Could be time to play tonight.

Yeah you can't solder Stainless Steel, you could do if it was chrome plated brass but you'd have to take off the plating first but getting enough heat in there to solder it would be next to impossible without melting the delrin isolator ring.

I would just clamp the leads in the holes myself

[Don]

Yeah, I'll make up some leads that can be jammed in with an 0.2 ohm coil - the nice thing about thick Kanthal is it takes quite a bit of melting. The dripper I'm thinking of doesn't have post holes but I'll work something out.

voltxamp=watt
something slightly lower or higher would work
too low means no power
too high means overload
