DC5V Inductance Capacitance Measuring Instrument Digital Transistor Tester LCD Frequency Meter USB Cable DIY Electronic Kit

DC5V Inductance Capacitance Measuring Instrument Digital Transistor Tester LCD Frequency Meter USB Cable DIY Electronic Kit DC5V Inductance Capacitance Measuring Instrument Digital Transistor Tester LCD Frequency Meter USB Cable DIY Electronic Kit Features: 1. Transparent acrylic housing prevents hand contact with the board, ensuring durability and aesthetics. 2. Multifunctional measuring instrument electronic DIY kit, simple to operate and easy to use. 3. Large, high-definition LCD display with clear digital and symbol display for easy reading. 4. Multi-function rotary knob for selecting different functions, making measurement more convenient. 5. Capable of measuring various non-polarized capacitors, polarized electrolytic capacitors, inductors, and frequency. Product Parameters: Power Supply: USB powered, DC 5V (DC power socket) Non-polarized capacitance measurement range: 1pF to 2200pF Polarized capacitance measurement range: 1uF to 12000uF Inductance measurement range: 1uH to 1H Frequency measurement range: 20Hz to 400kHz PCB size: 91*80mm Casing size: 106*91*28mm Usage Tips: 1. The kit is powered by 5V DC. Use a power supply with minimal noise and stable output. 2. Before powering on each time, all switches must be released. The display will appear approximately 2 seconds after powering on. 3. After the display appears, before installing the housing, adjust the potentiometer so that the voltage between pins 4 and 5 of the LM393 is 3.16V. 4. Rotate the potentiometer to the corresponding position for the component being measured. 5. When measuring non-polarized capacitors and inductors, the positive and negative poles do not need to be distinguished. However, when measuring frequency and electrolytic capacitors, the positive and negative poles must be distinguished and ensure good contact. 6. The decimals of the readings are not rounded or optimized for blurring. Some fluctuation in the decimals is normal. Packaging List: DIY Kit*1 _x000D_
