Capacitance Inductance Frequency Measurement Display DIY Electronic Kit PCB DIY Soldering Project Practice Solder

Descriere Capacitance Inductance Frequency Measurement Display DIY Electronic Kit PCB DIY Soldering Project Practice Solder

1. This kit is a multi-functional measuring instrument based 51 single-chip microcomputer design, which integrates capacitance measurement, inductance measurement and frequency measurement. It can measure various non-polar capacitors, polar electrolytic capacitors, inductors and frequencies.
2. Practice making DIY welding of parts, learn to understand the application of microcontroller knowledge and the measurement principles of frequency, capacitance and inductance.
3. High-definition liquid crystal display, large LCD display, digital symbols show clearly, easy to read.
4. With multifunctional rotary gear, you can choose different functions, measurement is more convenient.
5. Can measure various non-polarized capacitance, polarized electrolytic capacitance, inductance and frequency.

Supply voltage: USB power supply 5V ( power holder)
Measuring range of non-polarized capacitance: 1pF-2200pF
Polarized capacitance measurement range: 1uF-12000uF
Inductance measurement range: 1uH-1H
Frequency measurement range: 20Hz-400KHz
Usage tips:
1. The power supply voltage of the kit is 5V voltage. Try to use a power supply with less noise and stable output.
2. Before each power-, all switches must be popped , and the display will be displayed about 2 seconds after power-.
3. After the display, before installing the shell, adjust the potentiometer so that the voltage between the 4th and 5th pins of LM393 is 3.16V.
4. When measuring non-polar capacitors and inductors, the positive and negative poles are not distinguished. The frequency and electrolytic capacitors must distinguish the positive and negative poles. The contact must be confirmed to be good.
5. The decimals of the readings are not rounded or virtualized. It is normal for all decimals to jump
