Use the VW mode to start with. The first time you use your iTaste VV 3.0 start at 6 watts and vape. Move up the power in .5 watt increments and vape. The warmth of the vape will increase as well as the amount of vapor produced as you increase the watts. The taste will change as well with some flavors doing best at low power and some at higher power. Any power setting that you happen to like between no vapor and burnt is just fine.
Once you choose your favorite power level the VW mode will automatically adjust the vape to that exact warmth irrespective of the oHms of the head you are using in your juice delivery device. This is particularly handy as the oHms stamped on the head is very commonly off by ±.2 oHms and sometimes more which can sometimes make a noticeable difference in the taste of the vape.
In VV mode you can also adjust the warmth of your vape but VV does not do the oHms math for you. If you forget to adjust the settings for the oHms you can get a burnt taste, pop a coil or get very little vapor production depending on whether it is set too low or too high.
