A load regulation circuit used for calibrating a voltage drop tester includes a voltage control switch, a first resistor group, a power control switch and a second resistor group electrically connected to the first resistor group through the power control switch. When the voltage control switch is switched on to different positions, the first resistor group provides different loads and load voltages for the voltage drop tester. When the power control switch is turned on or off, the first resistor group and the second resistor group provide corresponding loads and load powers for the voltage drop tester to calibrate and correct operating parameter of the voltage drop tester. The load regulation circuit can simulate and replace different electronic device to calibrate the voltage drop tester. |
