EX-500-5 - ExperTune - Theory and Use


Objectives

This course will enable you to master the use of ExperTune software for control loop analysis, and teach you how to use the many powerful tools provided in the ExperTune package. It is a perfect occasion to familiarize and increase your knowledge of ExperTune. This is also a good opportunity for you to improve your control loop optimization skills.

This course is the same as Ex-501-3 and Ex-502-3 combined.
Who should attend

Anyone with a basic knowledge of instrumentation who wishes to use loop analysis and optimization software with PID controllers.
Schedule
