Notes
The Zerograph as well as the Centrograph are
instruments of very high precision, to calculate
intermediaiy consecutive times, i.e. when it is
necessary, in one single operation, to stop, go back to
zero and restart the seconds hand, for either sports use,
car racing, motorbyke, bicycle, or even to calculate the
production times of manufacturing process.
