Som e faults of the trad itional m ethod were ind icated. The analytical app lication of characteristic param eter was designed based on the graph ical programm ing language LabVIEW. Static param eters ( sensitivity, linearity, etc) and dynam ic param eters ( inherence fre- quency, damp, etc) w ere carried out on rea-l tmi e bym athem aticm ethod such as least-squares and sp line interpolation. The experi- m ental results show that the app lication has friendly user interface and is operated easily. The result is correct, the efficiency is h igher. So it can be competent for industrialm easurem ent. K ey word: virtual instrum ents; static characteristic; dynam ic characteristic; LabVIEW 0 , - , , , , [ 1- 2] , ) 1. 1. 1 线性度 , ,
