The following abbreviations are used in parameter names, figures, and other descriptions. These
abbreviations mean the following:
* “EU” stands for Engineering Unit. EU is used as the minimum unit for engineering units such as °C, m, and g.
The size of the EU depends on the input type. For example, when the input temperature setting range is −200
to 1,300°C, 1 EU is 1°C, and when the input temperature setting range is −20.0 to 500.0°C, 1 EU is 0.1°C.
For analog inputs, the size of the EU depends on the decimal point position of the scaling setting, and 1 EU is
the minimum scaling unit.
The following tables show the correspondence between the symbols displayed on the displays and
alphabet characters.
