4.6 Selection of Units
You can display system data in any of a wide variety of units. When you change units, your selection
will remain until you change it again. Unit selections are global, which means that all values of that
parameter type across the whole system will change to the chosen units. For example, changing the
temperature units to °C will display all temperature data in °C.
Data retrieved via RS-232 will always be in SI units regardless of the units chosen for
display. Also note that settings within dialog boxes used for changing system parameters
are entered and displayed in SI units. Units only affect the four data lines.
