<p>Features: 1. Avoid hand contact with the board, beautiful and durable.</p> <p>2. Multi-functional measuring instrument electronic DIY kit, simple operation, easy to use.</p> <p>3. High-definition liquid crystal display, large LCD, digital symbols show clearly, easy to read.</p> <p>4. With multifunctional rotary gear, you can choose different functions, and measurement is more convenient.</p> <p>5. Can measure various non-polarized capacitance, polarized electrolytic capacitance, inductance, and frequency.</p> <p>:</p> <p>Power supply voltage: USB-powered DC 5V (DC power socket)</p> <p>Measurement range of non- capacitance: 1pF~2200pF</p> <p>Polarized capacitance measurement range: 1uF~12000uF</p> <p>Inductance measurement range: 1uH~1H</p> <p>Frequency measurement range: 20Hz~400KHz</p> <p>PCB board size: 91 x 80mm</p> <p>Use tips:</p> <p>1, the kit supply voltage is 5V, try to use a power supply with fewer stray waves and stable output.</p> <p>2, each time before powering on, all switches should -up, and power on about 2 seconds before the display.</p> <p>3, after the display, before installing the , adjust the potentiometer so that the voltage between pin 4 and pin 5 of the LM393 is 3.16V.</p> <p>4, measure what components are rotated to the corresponding gear.</p> <p>5, measurement of non-polarized capacitance, inductance does not distinguish between positive and negative, frequency and electrolytic capacitors to distinguish between positive and negative contact to determine good.</p> <p>6, the tail number of the readings are not rounded and fictitious optimization, all the tail number has jumped is normal.</p> <p>Whether with a : with Case</p> <p>Material: PCB+components</p> <p>colour: As shown</p> <p>Package Contents:</p> <p>1 x DIY Kit</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +\/- 1-3cm.</p>
