Introduction
1.1 Product Description
The Model 07-444 Little Genius scanning densitometer is designed to be used with a Nuclear Associates
sensitometer to monitor film-processing performance. Little Genius is a battery and/or line operated unit
capable of automatically scanning 21 Step films and making single point density measurements.
The Little Genius measures and displays the step densities of a 21-step film. It calculates and displays
base + fog, maximum density, speed index, average gradient, relative speed and contrast index of the
processed film.
Model 07-444 allows the user to label and store measurement data for up to 20 film processors. The
measurements can be downloaded to an IBM PC compatible computer or printer via the RS-232
interface, located on the back panel of the units.
The stand-alone or graphics mode with its control chart features provides a quick method for tracking
daily film processor performance. Control chart values for 31 daily measurements with up to 20
processors can be stored in the Little Genius. Control charts may be as either index or gradient values.
Control charts and D log E curves may be output directly to a printer via the RS-232 interface.
