Problem with Fused Clapton resistance

[Dappel]

Hey ecf,

I got myself a dotmod V1.5 recently and decided it's time to try out a Fused Clapton Coil. I did 8wraps at 2.4mm with 26g AN80 and 36g NI80 as outer wire. After dry firing this build should be at around .19 to .22 ohm on a dual coil. It, however, reads at .16ohm on my ohm meter and .176 on my regulated device (planning to use it on a mech though).
Any ideas what might be causing the issue?

It's right on the nose. 26n80 2.4mm 8/7 wrap.. .34Ω each coil, dual at .17Ω

Hm, ok. Which Ohm reading should I trust tho? My ohm reader which reads it at .16 or my regulated mod (sigelei 150W TC) which reads it at .176? Any build seems to read differently on those two, it's always a difference of .015 to .02 ohm weirdly.

You will always have a fluctuation of +- .01 The Steam Engine calcs take into account 5mm legs on each coil. Shorter/longer legs then 5mm can toss your resistance a bit. Also double check your connections and everything like that. My ohm reader constantly reads .02 higher then my regulated deceives. If you breathe on your coil wrong you will change the resistance. I always go off my regulated device.

Neither.... unless you KNOW which meter is correct. Since you don't.. Assume the TRUTH is somewhere between the 2 readings you have.

Personally I would assume the lower resistance between the two meters is correct for battery safety but realistically 0.02ohm fluctuation is minimal. I've seen as much as that from one vape to another depending how warm the coil is when tested

8 wraps on a 2.5 gets you around the .2 ohm range. I used to build 26/36g N80 fused Claptons for my Petri, 8 wraps 2.5mm bit for my sigelei 100w which cuts off at .15. When it's below .20, the mod would read .1. Mine read .2 on the mod so I knew they were around .2ish. But yours is reading just fine at that ohm range.

I shorted my ohm meter across the 510 and it was .01 off
