Hello, This is my first post and although I'm new to E-cigs I'm not new to electronics so I hope I can shed some light on whats going on in your e-cig to help you better understand. So you put your meter on the atty and got a number on your meter....what does that actually say to you other than "its good" and what does the "beep" coming from your meter really mean?
With your meter set to ohms and the probes touching the center pad and the threaded area you will get a number (for simplicity lets say its 4 ohms) This number is only half of the equation you need in order to figure out whats happening. Now you set your meter to volts dc and read your battery at 4 volts dc (again theoretical) with these 2 numbers you can apply the following formula:
V2 / R = W
so 4volts squared is 12. 12 devided by 4 ohms equals 4 watts. So in this example the atomizer is dissapating 4 watts of heat to attomize the juice into vapor! Now lets say your battery is 4 volts but you have a suspected bad attomizer that reads 1000 ohms when you use your meter. Using the above formula that would be 12volts/1000 ohms =.012 watts. That means this attomizer would produce 200 times less heat to the juice which would make it useless.
So lets simplify:
If the resistance of your atty is 0 then its the same thing as putting a piece of metal from the positive part of the battery to the negative. The result is the battery overheating. (I used to make hand warmers as a kid buy taping a wire to the top and bottom of a D cell battery...got nice and toasty for a short time
)
If the resistance of the atty reads open or infinity (these terms simply mean there is no connection at all) then without any resistance, no watts are produced and its exactly the same thing as disconnecting the atty from the battery....its useless.
If I read correctly the average resistance is somewhere in the 3.5 to 8 ohm area depending on model of e-cig. That means that a good atty-battery combo should produce 2-4 watts of heat. Now obviously, 4 watts of heat produces more vapor but with the sacrifice of battery life...the same battery with an 8 ohm atty would last twice as long but produce half the vapor...make sense?
So, charge your batts and read your attys...the highest voltage batt with the lowest ohm atty should produce the best vapor! Hopefully this helps a little!
