Load Sequence Controller Family an Operators Manual

摘要

The advent of the micro-computer, and in particular its application to test and control instrumentation has resulted in the development of many highly sophisticated measuring instruments and controllers able to perform a very wide range of functions. In most cases the range is so wide that without recourse to appropriate manuals the average operator is unable to take advantage of more than a small percentage of the facilities available. While the family of micro-computer based instruments covered by this manual are essentially single purpose devices in the sense that each has been designed to perform a particular task, the full potential of their ability to perform these tasks will only be realized if careful attention is paid to the procedures discussed in this manual. The family of instruments covered by this manual comprises: (1) Single channel load sequence programmers used to generate the loade sequence signals to be applied to the input port of a servo-hydraulic testing machine, (2) Single and dual channel controllers which, in addition to providing the loade sequence signals, control the loads being applied to the test speciment by including a servo-hydra controller and manual valve controls, and (3) Eight-input data acquisition modules able to measure and store responses induced in the test specimen by the applied load sequence.
