| Abstract: | This paper introduces several problems affecting test precision in waterpower dynamometer usage. e.g. the check of torque consistency. the correct reading, prevertion of zero-place drift. selection of brilke arm force. protection of correcting arm blade and the dam ping of oil viscosity. The methods to improve test precision are put forward here. |
