The description of the flow-chart is very intuitive thanks to the symbols provided in the library

for state machine description. As seen in Figure 7 there is a direct correspondence between

the flow-chart and the described state machine.

Figure 7: Sequencing Description By State Machine

The description of comparison features for the tolerance window, and the reference data

memorisation is done following the methodology of decomposition into basic functions already

used in the start-up version.

Eventually, the complete schematic is represented in Figure 8, where the addition of the

autozero process and the non linearization feature is easily distinguishable from the start-up

version. The modular description and development of the application are very easy to manage.
