The resistance dynamometer working in the Mitaka No. 2 Ship Model Experiment Tank of the Ship Research Institute has a remote control equipment, an automatic balancing system and digital displays, In this paper the resistance dynamometer is discussed mainly from a point of view of dynamic characteristics. Transfer functions of balance and servo-moter systems are culculated. It was found that the transfer function of the dynamometer was expressed by the simple equation of the third degree in taking account that the time constant of the servo-moter system is nearly equal to zero and the characteristics of the dynamometer could be easily estimated from this equation of the third degree. Under the critical damping condition which is obtained by adjusting the oil-damper, the dynamometer has the moderate response with good accuracy in a case of usual resistance tests.
