Working Principle
Using a bridge circuit structure, the standard capacitor and the tested capacitor serve as the two arms of the bridge circuit. When measuring the capacitance value of the capacitor, close the test switch K, and the test voltage is simultaneously applied to the standard capacitor and the tested capacitor. The processor collects the current signals flowing through both via sensors and processes them to obtain the capacitance value and resistive component of the tested capacitor.
The fully automatic capacitance and inductance tester, due to the use of standard capacitors and synchronous sampling technology for the tested capacitor, is not affected by power supply voltage fluctuations; moreover, the measurement process is fully automatic, avoiding errors caused by manual operation, thus it has the characteristics of good stability, good repeatability, and accuracy and reliability
