WHERE can i go buy a multimeter. ill go get one .
OK i got a multimeter, now if someone would have the decency to tell me how to test these. thanks in advance.
Set your multimeter to "ohms". It will be that Omega symbol.
Positive probe to the center contact on the cartomizer connector, Negative probe to the threads.
Before you start, set to "ohms" and touch the meter probes together. It should read zero ohms. If it reads some positive value for ohms then just subtract that from your readings when measuring the cartomizer.
For example, touch the probes together and the multimeter reads 0.2 ohms. Check the cartomizer and it reads 3.6 ohms. 3.6 - 0.2 = 3.4 ohms for the cartomizer.
