you dont adjust the resistance. the resistance is set by the coil. type of wire,thickness number of turns etc... the vamo has VV and VW, not sure on the vmax. im just not a fan of anything that looks like a dildo, so i went with the MVP(VV, not VW) but it does not have a res check function like the vamo does, but i already have a meter, so its no biggie. FWIW, i just got the kamry K200VV/VW and a K100 mech and couldnt be happier. the befefit of VW is, you set the watts you want to use, and forget it basically. VV is more of a fiddle type of deal where you adjust the voltage to the proper setting based on the coil...
rule of thumb is add 2 volts to whatever res carto you have. so a 1.7 ohm carto would use 3.7-4.0 ohms
to figure out what wattage you are vaping at, here is how you figure it out:
V x V/res = wattage
so, 3.7x3.7= 13.69
13.69/1/7 = 8.05 this would be the wattage you are vaping at, so on a VW unit, you could set it at 8 watts, then leave it. no matter what res carto you use, it will automatically set itself to 8 watts or whatever wattage you want.
