1.2 Design and Function of the Scale Part
[374|376|378|703|704|264|274|284|285|954|957|959|963]

1.2.1 Design [374|376|378|703|704|284|285]

The scale consists of the following main parts: the frame with up to four load
cells, a display unit, a key panel and a power supply unit.

1.2.2 Function [374|376|378|703|704|284|285]

The action of a force causes elastic deformation of the load cell. A
corresponding analog signal is supplied, which changes linearly with the force
applied. This signal is measured and evaluated by the scale electronics and
displayed as a weight value. Figure 2: Functional diagram [704|284|285]
shows the functional diagram for scales with separated modules for
determining and
[374|376|378|703]
shows the functional diagram for scales with a single electronic module for
weight measurement and display.
