Diy Inductance Capacitance Frequency Meter Tester Kit Based On 51 Single Chip Mcu With Shell

Parameter : Board size : 6.8 8.5CM Supply voltage : DC5V or DC8-14V or AC7 to 10V Various gear range instructions : Inductance measurement range : 0.1H--------1H Small capacitance measurement range : 1pF-------2.2F (no polarity capacitor) Frequency measurement range : 20Hz ------400KHz (measured small signal) Electrolytic capacitance measurement range : 0.5F--12000F (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. Note : 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.
