Board size: 6.8*8.5CM
Supply voltage: DC5V or DC8-14V or AC7 to 10V

Various gear range instructions:
Inductance measurement range: 0.1μH--------1H
Small capacitance measurement range: 1pF-------2.2μF (no polarity capacitor)
Frequency measurement range: 20Hz ------400KHz (measured small signal)
Electrolytic capacitance measurement range: 0.5μF--12000μF (electrolytic capacitor)
F theoretical frequency measurement 0-500k, sampling error within a few 
hz, this function can be said to be attached, do not white, but there are certain requirements for the input signal, because the Schmitt trigger is not used, so it is only used to measure common mode Ideal waveform with less interference.


When the power is on, the LCD will probably have a white screen of about 2 seconds. This is because the program is designed like this. The system is powered on for 2 seconds. The system calculates some initial references that need to be used for subsequent measurements. The white screen interval is pressed except the power switch. The other switches are required to bounce. If there is a switch hold down, the subsequent measurement data will be inaccurate, remember!
After 2 seconds of the white screen, the LCD will display: F/C/L Tester, then you can start measuring the parameters of the component you want.
For example, if the non-polarity capacitor is measured, connect the “non-polarity capacitor test switch” after connecting the non-polarity capacitor. For example, if you measure the inductance, press the “inductance test switch” after connecting the inductor. The 5 function switches can only be used at the same time. Press one to test what is pressed, and the one that is not used is required to bounce.
When non-polar capacitors, inductors, and polar capacitors are tested, these components are connected to the test socket without polarity. The frequency test needs to distinguish the polarity.
If it is the first time after the kit is soldered, you need to adjust the contrast of the liquid crystal. After power-on for 2 seconds, adjust the 10K potentiometer on the back of the board to make the display effect of the1602 better.
