Actually, the choice between whether the Imperial measurement system or the Metric measurement system is initialized can be done on the Setting display screen page (though it is also a parameter setting). When this Setting page value is changed, so is the parameter. The heading on the Setting pages for most controls is Inch/Metric, and an entry of 1 sets and initializes the inch mode, while an entry of 0 specifies Metric mode.
Again, this Setting page value selects the desired measurement system mode from the instant it is selected – and it controls what happens during power-up. Regardless of which measurement system is in effect when the machine’s power is turned off, the selected Setting page choice will be instated at power up.
