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.

摘要： A ground test circuit for a power supply unit includes a sampling circuit, a converting circuit, a processing circuit, and a switch circuit. The sampling circuit detects a voltage difference between a first ground terminal and a second ground terminal. The converting circuit converts the voltage difference to a digital value. The processing circuit compares the digital value to a predetermined value. As long as the digital value is smaller than the predetermined value, the switch circuit allows an external power source to be connected to the power supply unit. Thereby, the ground test circuit controls the connection between the external power source and the power supply unit according to the result of comparison of values done by the processing circuit.
