Mathematical Function 2-18 Mathematical Function The NT31/NT31C and NT631/631C PTs have been equipped with a mathemati- cal function that automatically executes formulas which have been registered in the PT in advance with the Support Tool. The mathematical function can auto- matically perform data processing such as scaling in the PT and display the re- sults.

Page 282 Section 2-18 Mathematical Function Using Numeral Memory Tables Any numeral memory table can be specified as an operand. When a numeral memory table is specified, the number of words used in the calculation or the number of words stored as the calculation result depends upon whether words are allocated to the host.
Page 283 Section 2-18 Mathematical Function Using Constants Use the following ranges for the constants when specifying constants for oper- ands. –2,147,483,648 to 2,147,483,647 (8000 0000 to 7FFF FFFF hexadecimal) When constants are used, the number of words of operands is fixed at 2 words. 2-18-2 Data Flow in Calculations Up to 256 formulas can be registered in the PT’s mathematical table.
