Item Name: Soldering Iron Soldering Accessory Adjustable Temperature DC12-24V 72W T12-TR. Input Voltage: 12-24V (power not included)Type: Electric Soldering IronScreen: OLED100% brand new and high qualityModel: T12Size: as picture showsTemperature Range: 150-450 degreesMenu instructions:Press the knob to enter menu, it will shows 7 options:ACT: calibration ,HSL: brightness ,DMH: sleep ,LED: always on display ,LVF: power ,LAG: language ,RTN: returnACT: calibrationInsert the T12 tip to handle and power on, set the temperature at 300, until the temperature in "real-time temperature" is stably display at 300, at this time, use a temperature measuring instrument to measure the temperature of T12 tip and record it. such as the measuring temperature is 350, then the calibration value is 50.Calculation formula: calibration value=measuring temperature - setting temperature (Note: Before calibration, the value after calibration must be set to 0)HSL: brightnessbrightness adjustable range is 2-100 , 2 is darkest, 100 is the brightestDMH: sleepwhen screen is "DMH ON 5" ,It means that if the operator does not use the soldering iron for 5 seconds (automatically detect the use status of the soldering iron), the soldering iron will stop heating, and it will start heating again after picking it up.when screen is "DMH OFF",It means that the soldering iron will always be in working
