Description
DC5V High Digital Inductance and Capacitance Measuring Instrument Frequency Meter with Case
DC5V High Digital Inductance and Capacitance Measuring Instrument Frequency Meter with Case
Features: 1. Avoid hand contact with the board, beautiful and .
2. Multi-functional measuring instrument electronic DIY kit, simple operation, easy to use.
3. High-definition liquid crystal display, large LCD, digital symbols show clearly, easy to read.
4. With multifunctional rotary gear, you can choose different functions, and measurement is more convenient.
5. Can measure non-polarized capacitance, polarized electrolytic capacitance, inductance, and frequency.
Specifications:
Power supply voltage: USB-powered DC 5V (DC power socket)
Measurement range of non- capacitance: 1pF~2200pF
Polarized capacitance measurement range: 1uF~12000uF
Inductance measurement range: 1uH~1H
Frequency measurement range: 20Hz~400KHz
PCB board size: 91 x 80mm
Use tips:
1, the kit supply voltage is DC voltage 5V, try to use a power supply with fewer stray waves and stable output.
2, each time before powering on, all switches should -up, and 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.
Whether with a shell: with Case
