just wondering what the SVD shows on the LCD when atty has short circuit?? i just trying to rebuild heads for protank for first time and ive build 2 different heads and both times showing 0.8 ohms so wont fire. im using 30ga kanthal, first one i used 2mm silica with 5/4 wraps and second 3mm silica with 6/5 wraps. both showed up as 0.8 ohms. 0.8 ohms mean short or is there different display when short circuit?
