The Control and Protective Switching Device is widely used in motor control and protection. According to national and enter- prise related quality standard, electronic circuit board performance parameters test should be carried out. After passing, they were assembled into the device. A kind of electronic circuit board automatic test equipment about the control and protective device was introduced. The equip- ment consisted of the IPC, NI data acquisition card, signal conditioning circuits, auxiliary power supply and circuit board fixture. When sys- tem was testing, the LabVIEW developed applications fully controlled the entire test process and analyzed real time performance indicators by testing and loading a variety of signals, or using serial communication. The test system could take advantage of LabVIEW flexibility to adjust the software settings and develop new functional test man--machine interface. It provided an important tool for enterprise comprehensive product quality control and product improvement in later period. The practice showed that the device had high precision, reliable perform- ance, strong anti--interference and short test time.
