I recently got my first rba an aga-t+ and have set up a few wicks and coils on it. for the most part they have been working well as far as flavor and vapor production. my issue is with the resistance, on all the coils Ive made so far the resistance is all over the place. for example when not used overnight and before taking a vape check the resistance it will be very high like over 4 ohms. after i take a vape or two and it heats up it goes back to the normal 1.3 to 1.5 range. Im using a vamo to check the resistance. is this something I am doing wrong when building the coil, or is this normal for an rba. it has been working very well other than the resistance changing.
