Multi-functional measuring instrument electronic DIY kit, simple operation, easy to use. High-definition liquid crystal display, large LCD, digital symbols show clearly, easy to read. With multifunctional rotary gear, you can choose different functions, and measurement is more convenient. Can measure various non-polarized capacitance, polarized electrolytic capacitance, inductance, and frequency. Attention: 1. This product is a DIY kit and not the final product. 2. This welding project requires basic electronic knowledge and hands-on skills. 3. The delivery is in loose parts, which need to be welded and assembled by yourself. Some accessories are sent randomly and cannot be specified, which not affect the use. Power supply voltage:USB-powered DC 5V (DC power socket) Measurement range of non- capacitance:1pF-2200pF Polarized capacitance measurement range:1uF-12000uF Inductance measurement range:1uH-1H Frequency measurement range:20Hz-400KHz Use tips: 1. the kit supply voltage is DC
