1. Detection mechanism

The method of detecting a gauge capacitor with a resistor file. During measurement, the positive power source increases the power to the measured amphibious capacitor adapter through the standard resistor R0, starting with the moment of the increase in power, which, because of Vc0, presents "000". As VC rises, the representation value increases. When a VC / 2 variable resistor is present, the pressure gauge begins to render an overflow indicating "1". During charging, T is the time required to display the value from "000" to overflow, and the distance during this period can be measured by a quartz meter.

2. Test data for measuring capacitance using digital multimeter

When using digital multimeter to measure the capacitance of 0.1uf to 1000uf, select the resistor file, measure the limit of capacitance and the time of increasing electric quantity. This method is relatively simple and convenient, it is recommended that we use digital multimeter to test the safety capacitance.
