This is the same as the "resolution" or the "weighing
increments" of the weighing system.
Examples:
A weighing system with a "graduation" of 1 kg would start at 0
kg and then move to 1 kg, then to 2 kg all the way up to the capacity of the
weighing system
A weighing system with a "graduation" of 0.2 kg would start at
0.0 kg and then move to 0.2 kg, then to 0.4 kg all the way up to the
capacity of the weighing system
