As a general rule every vaporizer works using the same method - no matter who the manufacturer is. Vaporizing works by heating the herb to the perfect temperature so that the medical stuff evaporates without ignition. The best vapes will store all the vapor into a balloon but these are always much more expensive. If your vape doesn't have a preset temperature you may have to select the setting yourself. I recommend you use somewhere around 190.
The hot spot for vaporizing is between 170 - 200 Celsius. Many users vaping herb can find that they just can't achieve the full body effect they are after and turn the temperature up a little higher. This is not that bad a thing to do, when the herb is ignited in a roll up the temperature is extremely high and will cause damage to your lungs. With a vaporizer you can actually begin to burn the herb and get a stronger high with less body damage.
