DC5V High Precision Digital Inductance and Capacitance Measuring Instrument Frequency Meter

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 various non-polarized capacitance, polarized electrolytic capacitance, inductance, and frequency.

Specifications:

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 pop-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: without Case / with Case
