CH1 Process value (PV) scaling value
When the temperature process value (PV) scaling function is enabled, a scaled temperature process value (PV) is stored. For
details on the temperature process value (PV) scaling function, refer to the following:

Description
This bit turns ON when the simultaneous temperature rise parameters
the simultaneous temperature rise AT.
This bit turns ON when the simultaneous temperature rise parameters
calculated by the simultaneous temperature rise AT.
This bit turns ON when the simultaneous temperature rise AT was not able to be executed.
