EU
*1 "EU" represents one engineering unit. EU (e.g. °C, m, or, g) indicates the smallest engineering
unit.
EU size depends on input type. For example, when input temperature range is set to -200°C ~
+1300°C, 1EU is 1°C; and when input temperature range is set to -20.0°C ~ 500.0°C, 1EU is
0.1°C.
With analog input, EU varies according to the decimal point of the scaling setting, and 1 EU
becomes the smallest scaling unit.
