05 Main Menu (Page 2)Heater Control (Operation modes)The mod can be used in up to 5 operation modes. The mode can be selected in this menu.The default operation is either standard (0, power setting) or temperature controlledvaping (1). With the “Expert Mode” (Extended Functions Mod-Menu) enabled, additionaloperation modes are Heater Protection (2), Power Boost (3), and Bypass (4, mechanicalmod). With Expert Mode disabled, the menu options 2..4 are masked out. Battery StatusThe Check Battery item shows the battery voltage with little current drained (Ub0) and thebattery voltage under load during the last puff (UbL). The difference is the voltage dropwithin the battery and contacts. A high drop (>0.4V) indicates a poor battery or contactproblems.Please note that every battery has an inner resistance and that therefore the voltage at its contacts alwaysdrops when current is drained. The more current is drained, the higher the drop will be. Always rememberthis behaviour.Commonly OEM batteries of size 21700 and 20700 have inner resistances of about 8mOhm up to 25mOhm.Generally speaking, the batteries with high capacity have higher inner resistance and those with lowercapacity also have lower inner resistance. 0. Standard ModeIn the standard operation mode the wattage selected in the power setting menu is applied to the coil, unlessthe voltage would be greater than 12V or the current greater than 22A, which depends on the coil resistance.For example with a coil resistance of 4 Ohms and a power setting of 40W, the required voltage at the coil is12.7V. With 4 Ohms the maximum wattage is 36W ((12V)²/4R=36W). Or, if the coil resistance is 0.1 Ohm, themaximum power is 48.4W, because (22A)²*0.1Ohm=48.4W.As can be seen from the examples, with high coil resistance the power is limited by the maximum output voltage of 12V and with low resistances by the maximum output current of 22A.The fact is also reflected in the feature list: A power of 80W is possible from 0.18 to 1.5 Ohms.Nevertheless, resistances of 0.05 to 5 Ohms are possible, but at a reduced power.1. Temperature controlled vapingIn this mode the mod will regulate the temperature of the coil to the pre-set value, exceptthe power setting is too low to achieve the temperature. So please note to adjust thepower setting to a value high enough, if you choose temperature controlled vaping.Otherwise the temperature regulation changes to a temperature limitation mode.When Hctrl is set to 1, the menu directly jumps to the selection of the wire type. Here theuser can select between dicodes-wire (NiFe30), Nickel 200, Titan, Stainless Steel (SS316L),Stainless Steel (SS304/Inox) and “Other”. With “Other” selected, the temperature coefficientdefined in the Extended Functions Menu / Heater Menu under item “Tmp. Cof” is used.The value of the selected coefficient is displayed behind “Wire”. For commonly used wires,the predefined coefficents are: NiFe30=320, Nickel200=620, Titanium=350, SS316L=92 andStainless Steel (SS304/V2A/INOX)=105. Note that there are different alloys for Titaniumand Stainless Steel on the market, so the predefined values can deviate from the actualwire-value you use.
…
The range for the temperature coefficient is from 50 to 650. The number describes 10 times the percentagechange of a wire’s resistance when the temperature rises by 100°C. For example a 1Ohm coil at 20°C of NiFe30(Tmp.Cof=320) will increase to 1.32 Ohm at 120°C and 1.64Ohm at 220°C.
