4. PROCEDURES
Further the normal refuelling, there are three different possible procedures:
Reading from the absolute total counter
Computing head set-up (changing the configuration parameters), price change
Metrical office (anomaly simulation)
To start a procedure, operator has to push one of the push-buttons on the set-up board;
display will show the following notice:
Push on one of the set-up buttons, to activate the relevant
procedure; push-buttons are available on the printed circuit
connected to the same cable of the display:

Reading from the absolute totalizer
The absolute totalizer is a counter which cannot be reset (to zero) and allows to store and
display the quantity delivered in Kg or Smc on 10 digits. Since it is not possible to dispose of
such an extended display, digits are subdivided into groups and visualised as follows:
