The invention relates to a dynamometer instruction loading method used to the loading test of the starting process of a starter, which belongs to the field of the engine testing technology. The invention is characterized in that according to the process documents of trial running and the real-time collected dynamometer signals, with a clock as the drive, a computer software module makes the real-time judgment on the present loading state, adopts the adaptive parameter adjustment, and produces the loading instructions and sends the actual instructions to the dynamometer in real time. The methodcan solve the problem of the prior art of the failure of the starting test, which is caused by the overtolerance in rotating speed and the over-limit in torque which are easily appeared in the courseof the loading in the starting process of the starter.
