Hi, I have a paranormal 250c, and i would like to check the accuracy of the temperature control. I made an SS316L 0.5ohm spaced coil and tried to measure its temperature with a digital probe (I put it inside the coil), but I was not successful.. the measured temp fluctuated too much and was never close to that set into the dna250 screen Should this measurement method work? Thanks, Robs
