Abstract: In the spectrometric apparatus disclosed herein, a monochromator provided with a stepping motor drive is controlled in a sequence of scanning operations by a memory which can be loaded by means of simple punch cards. The memory holds a plurality of multi-bit digital words, each word comprising a first portion which can designate a rate of scan and a second portion which can designate a destination value, stated in terms of wavelength. Each stored digital word also includes a plurality of control bits which affect the operation of the spectrometric apparatus and which can also be used for controlling apparatus external to the monochromator, e.g. a strip chart recorder.
