at OP.
It seems that you have the meter. Next time you suspect atty is dead, just measure it as you did before. If meter reads anything above 100 ohms, the atty is dead (heating coil is gone). If it reads less than 1 ohm, atty is shorted - do not use, the spring will collapse.
Cheers.
BTW I'm on the 5 week with Ikenvape i06 1.5 and 3.5 ohm atty's. Still going strong as new. 99% Isopropyl bath once a week, let it dry, no dry burn, marinade with juice 10 minutes, blow excess, put it on REO, squonk, and vape into week long coma again.
