6. Working principle

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

Due to the synchronous sampling technology of the standard capacitor and the capacitor under test, it is not affected by power supply voltage fluctuations; moreover, the measurement process is fully automatic, avoiding errors caused by manual operation, thus featuring good stability, repeatability, and accuracy.
