Abstract
Abstract An arrangement for controlling the scan of a spectrometer employs a computer and associated equipment for initiating one complete scan of the spectrometer. During this scan where partial ranges of signal values are detected, said ranges being of particular interest, repeated scans of these ranges occurs until a sufficient number to provide useful information is obtained and, thereupon, the continuous scan of the spectrometer is continued. The equipment employed includes address registers and comparison circuitry for indicating and storing the addresses of those signal values which the computer has selected after a determination has been made that a partial range exists. Where signal values far exceed the threshold value which defines a partial range, no repeated scanning is employed or is necessary.
