The invention discloses an airplane hydraulic system servo valve static tester and a testing method. The tester comprises a main control unit, a current display unit, an automatic signal unit and an interface unit. The main control unit comprises a mode selection module, a current selection module and a function selection module, supports Q calibration, Q0 calibration and delta P calibration, and is used for selecting a servo valve test mode and controlling an input signal; the current display unit is used for displaying the input current of the servo valve, monitoring the current change in the test process, and calibrating the current of the servo valve and reversing the servo valve; the automatic signal unit is used for providing a current signal and a frequency signal required by automatic testing and running-in of the servo valve; and the interface unit is used for accessing external equipment required by testing. According to the static tester, multiple functions are integrated, function switching is carried out through the switch, calibration is carried out through the potentiometer, the operation process is simplified, meanwhile, the precision is high, the adaptability is wide, and small signal measurement can be more accurate.
