Tesla 120w resistance reading off?

[jlwiseman]

Hey guys. I have a tesla metal 120w box mod. It fires atomizers 0.2-3.5ohm...I recently started building on my rda. So I get out the ohm reader and build a 0.25 ohm 28ga twisted dual coil setup. Comes out beautiful, however when I stick it on the mod, I get an atomizer short message. Throw it back on the eleaf ohm reader, 0.25 ohm. So I build another coil at around 0.33ohm, toss it on the mod and it vapes. But the display reads it as a 0.2 ohm coil. So now, my wattage calculations are all off, and I get a much warmer vape than I was shooting for at any given voltage. Is this something I might could remedy? Or am I stuck living with it and always building up a tenth of an ohm? Which then throws the calculations the chip does over and gives me a different vape at a desired voltage/wattage.
