摘要： A resistance determining system is used to determine an offsetting resistance of a mainboard to establish a predetermined offset voltage. The system includes an input equipment, a single-chip, and a resistor. The input equipment sets a predetermined standard voltage of the mainboard. The resistor supplies the mainboard with various resistances, to adjust real output voltage of the mainboard. The single-chip monitors the real output voltage of the mainboard, and adjusts the resistance of the resistor until the difference between the real output voltage and the predetermined standard voltage is equal to a predetermined offset voltage.

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.
