	The chapter describes the theoretical and experimental investigation of the influence produced by bias error during capacitive accelerometer installation on results of vibration acceleration measurements, which determines the origin of additive error component in the process of measuring conversion of a nonelectrical value into an electrical one. It is shown that this error appears during the installation and mechanical fixation of an accelerometer at the measurement object, and with normal deviation from the perpendicularity of the accelerometer, it may reach 0.855 m/s2, being at its maximum in the horizontal measuring axis. The authors proposed the method for lowering the accelerometer installation error and the structural diagram of intelligent self-calibrating measuring channel of vibration acceleration, which ensures automatic deletion of this error component from measurement results.
