What does tcr even do?

[ItsHaiku]

Hey all, I have Smok GPrif using SS coil im looking at tc mode under that it's adjust tcr(which threw me off / confusing), like the title says and how do I know if I need to up or down it on adj tcr?

Example not from my box mod: adj tcr 0.00095, what's that number even mean?

TCR is Temperature Coefficient of Resistance which is the resistance change per degree Celsius. That's why it's important to start with a room temperature Atty/coil(s) as most mods makes their initial resistance reading and assume room temperature. The ability to tweak/change the TCR enables you to fine tune it for a closer true temperature. Personally, I just adjust the set point temperature to the vape I want without concern of what the true temperature of the coil is verses what's displayed. Since I like a ever so slightly warm vape I'm not concerned about roasting the wick.
