[An automated unit for manual photometry and morphometry]

An automated unit for manually controlled photometry and morphometry is described. It enables the operator to carry out photometrical measurements according to the plug-method and morphometrical measurements with the help of an object-micrometer or some kind of a grid. The data obtained are stored in the "Elektronika D3-28" microcomputer to be statistically evaluated after the end of sampling. New variables can be obtained defined by the user as a product of some source variables or their inverses. The data and control structures of the system are described in detail.
