1.2 Structure and function of scale section
1.2.1 Structure
The scale basically consists of the following parts:
 Base frame with up to four load cells
 Display unit with keypad
 Power supply (batteries, optional power pack)
.
1.2.2 Function
The effect of weight on the weighing surface causes elastic deformation of the load
cell(s) underneath. They produce an electronic analogue signal which shows linear
variation in relation to the application of force. This signal is measured by the weight
calculation system, analysed and displayed as a weighing value. Figure 2 shows the
function chart for scales with separate electronic modules for weight calculation and
display. Figure 3 shows the function chart for scales with one electronic module for
weight calculation and display.
