DC5V Digital Inductance Capacitance Meter with Case Description

DC5V Digital Inductance and Capacitance Meter with Case Description
Features: 1. Avoid hand contact with the circuit board, neat and clean.
2. Electronic DIY kit for multifunctional measuring devices, simple operation, easy to use.
3. High-resolution liquid crystal display, large LCD, digital symbols are clearly displayed and easy to read.
4. With the multifunctional rotary dial, you can select different functions, making measurement more convenient.
5. Can measure various non-polarized capacitances, polarized electrolytic capacitances, inductances, and frequencies.
Specifications:
Supply voltage: USB-powered, DC 5 V (DC wall outlet)
Measuring range for non-capacitive capacitances: 1 pF ~ 2200 pF
Measuring range for polarized capacitances: 1 µF ~ 12000 µF
Measuring range for inductances: 1 µH ~ 1 H
Frequency measurement range: 20 Hz ~ 400 kHz
Board size: 91 x 80 mm
Application tips:
1. The kit's supply voltage is 5V DC. Try to use a power supply with less stray voltage and stable output.
2. Before each power-up, all switches should be in the up position, and the device should be powered on for approximately 2 seconds before the display appears.
3. After the display appears, before installing the case, adjust the potentiometer so that the voltage between pin 4 and pin 5 of the LM393 is 3.16V.
4. Measure which components rotate to the corresponding gear.
5. Measure the non-polarized capacitance. Inductance does not distinguish between positive and negative. Frequency and electrolytic capacitors distinguish between positive and negative contacts to determine good contact.
6. The final number of the measured values is not rounded and is fictitiously optimized. All broken end numbers are normal.
