6. Working principle

The capacitance bridge adopts a bridge circuit structure, with the standard capacitor and the tested capacitor as two arms of the bridge circuit. When measuring the capacitance value of the capacitor, close the test switch K, and the test voltage is applied to both the standard capacitor and the tested capacitor simultaneously. The processor collects the current signals flowing through both via sensors and processes them to obtain the capacitance value of the tested capacitor.

Due to the use of synchronous sampling technology for the standard capacitor and the tested capacitor, it is not affected by power supply voltage fluctuations; in addition, 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.
