    摘要: A measurement circuit includes a switch unit with a number of keys selectively pressed to output different resistance regulating signals. A resistance setting circuit receives the resistance regulating signals and connects different resistances to a voltage circuit and a current circuit. The voltage circuit outputs different voltages. The current voltage receives a voltage from the voltage circuit and outputs a current to a capacitor. A detecting circuit measures a temperature of the capacitor and outputs the temperature to the resistance setting circuit. The resistance setting circuit compares the received temperature with a preset temperature. If the received temperature is equal to or greater than the preset temperature, the resistance setting circuit outputs short-circuit information of the capacitor. If the received temperature is less than the preset temperature, the resistance setting circuit outputs normal information of the capacitor. A display unit displays the information of the capacitor.
