The unit for superheated steam specific enthalpy calculation is set up here.
Superheated steam specific enthalpy submenu screen
←Unit option select setup
For details of option setup, see “(2) Option select setup screen (SELECT)” on
page 46.
The unit you can choose from are “kJ/kg”, “J/g”, “kcal/kg”, and or “cal/g”.
※ The unit to be set is that of the specific enthalpy displayed in the RUN mode.
※ Depending on the unit chosen here, the numerical format (number of
decimal places) of specific enthalpy shown in the RUN mode varies.
When you modify it, carefully take into account the count capacity and
the number of decimal places to be shown.
