This course offers help if you are responsible for the measurement or calibration system in your company, regardless of what you want to have calibrated. You learn to determine yourself which instruments need to be calibrated and how often, but also which instruments do not need to be calibrated. You learn the background of, and the rules regarding, "acceptable traceability".
