PURPOSE:To eliminate area not capable of an operation by using a table, where lattice points are provided on boundaries, in the operation device which has a table for two variables and performs the table interpolating operation. CONSTITUTION:The temperature signal from a temperature detector 1 and the pressure signal from a pressure detector 2 are inputted to a microcomputer 3. The microcomputer 3 uses the table of specific weight to temperature and pressure to use a specific weight with the table interpolating operation. In this case, the lattice points of the table are provided on boundaries (curve of saturated steam pressure) to eliminate the areas not capable of the operations. |
