1. In a method of using a programmed digital computer to control the measurement, storage and analysis of a multiplicity of measurements, said computer having data storage means for storing measurement data, and means for controlling the operation of an apparatus coupled to said computer, said apparatus including means for performing a multiplicity of measurements and communicating the resulting measurement values to said computer, the steps of:

  • establishing a set of processes which can be run under the control of said computer, each process having a predefined set of process parameters which control the operation of said apparatus;

    establishing a multiplicity of process definition data structures, including a measurement definition data structure within each process definition data structure;

    establishing a set up program for interactively performing the steps of;

    selecting one of said processes;

    defining for said selected process, a subset of the measurements which said apparatus can perform, and storing a representation of the selected subset in said measurement definition data structure for said selection process;

    wherein said set up program includes means for defining different subsets of measurements for each selected process; and

    establishing an operator process control program for enabling interactive computer controlled performance of the steps of;

    selecting one of said processes;

    running said selected process, and storing the measurement values conveyed by the apparatus to said computer in said data storage means;

    wherein said processes each include means for accessing the corresponding measurement definition data structure and for controlling the operation of the apparatus so that only the measurements specified in said measurement definition data structure are performed and so that only the measurement values corresponding to the measurements specified in said measurement definition data structure are stored in said data storage means.
