test objects are gearbox solenoid valve and valve plate of vehicles. Set the current of solenoid valve by solenoid valve actuator and the oil pressure of solenoid valve by hydraulic station; determine the qualification of product performance by virtue of current-voltage curve, curve repeatability, response time, etc.
1. Standardized high speed acquisition module
2. Self-developed solenoid valve actuator making current control more stable and accurate
3. Accuracy of analysis results guaranteed by reasonable analysis algorithm.
