A voltage measurement apparatus includes a power interface, first and second voltage detecting modules, first and second driving modules, and first and second indication modules. The first voltage detecting module compares an output voltage with a first reference voltage, to determine whether the output voltage is greater than the first reference voltage. The second voltage detecting module compares the output voltage with a second reference voltage, to determine whether the output voltage is less than the second reference voltage. The first indication module indicates the output voltage when the output voltage is greater than the upper limit voltage or less than the lower limit voltage. The second indication module indicates the output voltage when the output voltage is less than or equal to the upper limit voltage and greater than or equal to the lower limit voltage.
