I bough this Snowwolf Vfeng mod for my DMT cart, but I know nothing of these mods and how under what settings to use them. Here are the specs if the mod:

Specifications: Wattage Range: 10.0W-230.0W Input Voltage Range: 6.4V-8.4V Output Voltage: 1.OV-7.5V Resistance Range: 0.052-3.009 Operating Mode: POWER/SS/Ti1/Ni200/TCR Temperature Range: 100°C -300°C/200°F-570°F

In settings, it has 5 modes:

POWER: here i can set the WATT up and down, it is by default at 40

SS: has 3 subcategories under it, SS304, SS316 and SS317. When I select any of these, the display now shows Temperature, I use Celsius

TCR: here I get prompted with M1, M2, M3, M4 and M5. If i select any of these, I get prompted with setting the TCR, which is by default TCR=0.0033

Til: on this mode I get the temperature again on the main screen

Ni200: on this mode I get the temperature once again.

I have no idea what all this means and how to set it and why. Can anyone help me please?
