Theory Of Operation: a rocket engine thrusts against a water filled syringe. This produces pressure readings on a connected pressure gauge.
理论的运作：一火箭发动机推力对一个充满水的注射器，这产生的压力读数，就一连接压力计。

China, the method of calibrating measuring gauge that measures engine thrust by using weights, lever systems etc has been long used and still finds widespread use.
该装置模拟发动机推力，用标准推力表对工作推力表在测量范围内任意需要点上进行校准。
