charging.C(uF)-correction: This function is used to correct the measured value of the high-capacity capacitance, which is set to 0% by default. This means that there is no correction and is set from-0.2% - 8%. A value will reduce the measured value of the capacitor and a value will increase the measured value of the capacitor.Power Supplys: Type-C 5V power supplys, and compatible with 9V battery power.English Version Function:DS18B20 Function: The DS18B20 is a temperature sensor that uses a single bus communication method to transfer data and has the same package as the triode(TO-92).IR_Decoder: The IR remote controller decoding function supports two IR remote controller coding formats. All values of the IR function are in hexadecimal format. The IR decoding function only supports single button mode, not continuous mode.IR_Encoder: The IR remote controller encoder function requires an infrared LED. The tester can control this infrared LED and thus implement an infrared remote controller function. As the tester can only provide a maximum drive current of around 6mA, the control distance cannot be compared to that of a normal infrared remote controller. The IR remote controller encoding supports two formats, the same as the IR remote controller decoding format described earlier.Other Functions:FrontColor, BackColor, etc.Specifications:Name: Transistor TesterMaterial: printed circuit board+plasticsType: English Version, Russian Version (Optional)Display: 1.77inch TFT displayInput voltage: DC5VOperating voltage: 30mA approx.Item size: 82.2* 61.3* 29mm/ 3.24* 2.41* 1.14inItem weight: 47g/ 1.66ouncePackage size: 95* 95* 30mm/ 3.74* 3.74* 1.18inPackage weight: 76g/ 2.68ouncePacking List:1* Transistor Tester
