Brief description of the display module
Introduction
The display modules belong to the family of seca electronic modules and are used to display a
weight measured with a suitable module and transferred via the SeSAM bus (Seca's Serial
Autoconfiguring Multicontroller bus). Furthermore, the display modules accommodate the operating
elements and can process the weight (hold, tare, etc.).
The following block diagram shows the most important function blocks of the display modules:
