Digital LCD Frequency Counter & Capacitance Meter Tester Kit - Accurate Hz & Capacitance Measurement for Electronics, DIY Projects, and Electrical Testing

Product Description

Features:Transparent acrylic shell, avoid hand contact with the board, beautiful and durable.Multi-functional measuring instrument electronic DIY kit, simple operation, easy to use.High-definition liquid crystal display, large LCD display, digital symbols show clearly, easy to read.With multifunctional rotary gear, you can choose different functions, measurement is more convenient.Can measure various non-polarized capacitance, polarized electrolytic capacitance, inductance and frequency.Specifications:Power supply voltage: USB powered DC 5V (DC power socket)Measurement range of non-polar capacitance: 1pF~2200pFPolarized capacitance measurement range: 1uF~12000uFInductance measurement range: 1uH~1HPCB board size: 91 * 80mmTips for use:1, the kit supply voltage is DC voltage 5V, try to use a power supply with less stray waves and stable output.2, each time before power on, all switches should be popped up, power on about 2 seconds before the display.3, after the display, before installing the shell, adjust the potentiometer so that the voltage between pin 4 and pin 5 of the LM393 is 3.16V.4, measure what components are rotated to the corresponding gear.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.6, the tail number of the readings are not rounded and fictitious optimization, all the tail number has jumped is normal.Package include:1* Capacitance Meter Frequency Tester Kit
