BASELINE CORRECTION FOR UV SPECTROMETER

摘要

In a device in which an independent variable is stepped or scanned between a first limit and second limit and in which device there is an error which is a function of the independent variable, error correction is obtained by storing correction values, preferably of an incremental nature, for each of a plurality of steps of the independent variable, establishing location marker which can be identified as different from the error correction data, moving the location marker so as to always be adjacent the error correction for the current position or step of the independent variable and reading out the error correction at the point of the location marker.
