Claim Text:
1. A testing apparatus for testing a circuit board comprising electrical contacts, the testing apparatus comprising: a testing device comprising two probes and at least one measuring meter, wherein a distance between the two probes is adjustable and each measuring meter comprises at least two input terminals; a position adjusting device aligning the electric contacts of the circuit board with the probes; a lifting device bringing the probes into electrical contact with the electric contacts of the circuit board; a storage device storing a circuit schematic diagram and a circuit wiring diagram of the circuit board, wherein the circuit schematic diagram of the circuit board schematically shows connections among each electrical contact of the circuit board to illustrate a working principle of the circuit board, and the circuit wiring diagram shows an actual wiring pattern of the circuit board; a processor; and a testing system executed by the processor, the testing system comprising: a circuit analyzing module that matches the circuit schematic diagram with the circuit wiring diagram to determine a location of each of the electric contacts on the circuit board and determines a predicted voltage of each electric contact; a meter choosing module that chooses one of the at least one measuring meter according to a characteristics of the circuit board to be tested and connects the input terminals of the chosen measuring meter with the probes; a probe regulating module that regulates the distance between the two probes to a distance between the electric contacts; a position adjusting module that controls the positioning device to align the electric contacts to be tested with the probes according to the location of each of the electric contacts, the predicted voltage of the electric contacts, and the connections between the probes and the input terminals of the chosen measuring meter; and a test controlling module that controls the lifting device to bring the probes into electrical contact with the electric contacts to be tested to make the chosen measuring meter to test the characteristics of the circuit board.
