Function introduction: This kit is a multi-functional measuring instrument designed based on the 51 microcontroller that integrates capacitance measurement, inductance measurement and frequency measurement.It can measure non- capacitances, electrolytic capacitances, inductances and frequencies. DIY welding practice production of spare parts, learn and understand the knowledge application of microcontroller and the measurement principles of frequency, capacitance and inductance.Kit name: -053 Capacitance and inductance frequency meter kitSupply voltage: USB power supply 5V (DC power socket)Non- capacitance measurement range: 1pF~2200pF capacitance measurement range: 1uF~12000uFInductance measurement range: 1uH~1HFrequency measurement range: 20Hz~400KHzMaterial: abscolour: As ShownPackage Contents: 1 x Capacitance and inductance frequency meter kit1 x Casing (delivered as spare parts, some accessories are sent randomly, Cannot be chosen the specific accessories.which does not affect the use)Only the above package content, other products are not included.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.
