Resistance ohm numbers changing

[gabewiththedripbox160]

Hey there people of the vaping world. love you all. anyways. is it normal for my resistance ohm number to be changing from .45ohm- .48ohm?
help needed
thanks

Hi and welcome to the Vaping Underground!
A few hundreds of an ohm fluctuaction can be considered normal, in practice.
Some resistance materials (stainless steel for instance) increase resistance when the temperature raises - it's how temperature control works, by the way.
Some others (Kanthal, nichrome) don't
So if you're using Kanthal and your coil resistance raises significantly (tenths of an ohm) double check the connections: atomizer properly screwed in the mod, screws in the atomizer itself properly tightened (if it has any), and so forth

Yes, a 0.03ohm +/- change is not much to worry about, especially when you add in these factors.

1) Resistance Reader in your mod is not 100% accurate nor does its calibration stay the way it was from the factory forever.
2) Resistance in all wire increases with heat, as stated above this is how TC mods work to guess temp of the wire, by the resistance of it.
3) Resistance in wire increases with use, this is a result of heating and cooling, it is normal wear and tear, as metal is heated and cooled it becomes tempered and begins to crystalize at the molecular level, thus making it harder for electrons to pass through it due to those crystals over time.

It would be alarming and something to investigate if for instance firing a coil that reads 1.0ohm, then the next firing it reads 0.5ohms, then the next firing 0.25ohms, or vice versa resistance drastically increases, in those instances then you have a connection problem, or if you were already at a 0.10ohm reading then all of a sudden you had a 0.05ohm reading and the mod will not fire at that resistance or you were on a Mech mod would it be a problem and would have to tear things down to find the connection or short problem.

Most was all started as culprits, also that the coils are glowing evenly. In this case, abit of strumming and pinching the coil will fix this issue.

But xpen stated correctly. A few hundredths of an ohm is ok.

WOW~ You are so patient, bro

3yrs working in a vape shop you learn patience and just about see every error or problem that comes walking in the door =D
