I have a vt133 and i've had what i considered problems with my crown tank since day 1. WHen I attach the atty ill see the correct ohms reading for a flashof a second itll flat 0.25 or 0.24 (for ss coils then settle at 0.29). Thats ok i can accomodate for that with wattage. Still not sure why. I figured it was thess coils with nickell egs Well I am trying to run the nickel 0.15 coil and it clocks in at 0.24 cold. I can run it like that and im not sure that the temp readouts are or are not accurate. What is going on here? Also i set my mod resistance using one of those dna calibration copper pins you screw in but my kanthal readings will be off by 0.01 to 0.02 compared to my other non dna ohms readers and independent cheapo chinese ohms reader. The real issue is the crown tank, i have my heart set on it, ive used it since cyber monday, its a powerhouse never gives me problems and i refill like 4x a day. Should I get a different tank, do these tanks act funky? WHy is it tha tI see the correct ohms flash for a millisecond sometimes when i attach an atty for instance in wattage mode the ss atty willl read 0.24 then instantly go to 0.29 But this ni200 is a proble (maybe). Im just dialing it in starging lower with wattage and temp to accomodate the variance but im not sure i should be, is this some tpye of internal calculation? Does anyone with a crown and dna75/133/200 actually get 0.15 ni200, or 0.25 ss316 ohms readings on their cols?
