The mass of the sensor often have some effect on dynamic characteristics of the structure. This paper proposes a new method for compensation of sensor's mass effect in FRF measurements. In the method, inertial force of the sensor's mass is regarded as external force acting on the structure; FRF is corrected so as to remove the external force effect. The compensated FRFs of an accuracy are evaluated by a Reliability Factor which it is installed in this paper. The compensation method for the use of multiple sensors is also presented. The method is validated by applying it to a brass plate structure. The usability of the method is demonstrated via measuring FRFs of a car body.
