MEASURING AMPLIFIER WITH BACKGROUND ADJUSTMENT AND METHOD THEREFOR

摘要

The present invention relates to a method for performing background correction and adjustment to the measuring amplifier (103), and measuring amplifier of the above type for using the background correction and adjustment. The measurement amplifier amplifies the one or more measurement signals (111) of the at least one sensing element (102) using at least one amplifier device 108, digitizes, and processes. The amplifier device can be temporarily replaced by the additional amplifiers 107, which allows the continuous calibration of the amplifier device, and adjust if necessary. When the correction is determined so as Zero error amplifier amplify the error device but also reliability. In addition, the amplifier unit is directly corrected, not indirectly calibrated. Thus, a high accuracy measurement is achieved without the need for interruption. In addition, more generally, even if the amplifier of the measuring amplifier having a plurality of channels, only one stage is required.
