Computer-Aided Optimum Design of DC Measuring Instruments Using the D´Arsonval Mechanism

A computer program has been developed for optimum design of dc measuring instruments that use the D´Arsonval mechanism. The computer selects specific components, mostly from a standard set, to produce an optimum design satisfying given performance specifications and constraints. The program allows the designer to interact with the computer and limit the choices available to it. It also enables the designer to conduct a number of useful design studies without having to build and test a large number of prototypes. The program can be accessed from a remote terminal and gives the answers very readily resulting in a substantial saving in engineering time.
