Abstract： Aiming at achieving static test automation and improving test accuracy and stability，an automatic static test method was proposed. A/D module with high frequency and high precision was applied to collect signal of oil pressure sensor，and hydraulic system was controlled by programmable logic controller（PLC），which was used for lower computer. Upper computer set control system、measurement system and data storage system as a whole，the static test automation was realized. The test results indicate that the system can make efficient and precise static test.
