Abstract
Apparatus and method are disclosed for calibrating a load cell such as a load cell used in apparatus for measuring the forces applied to a pull tab during the formation of an opening in a container lid. The load cell first transmits a signal to a computer-recorder which is indicative of a no force applied condition. A known maximum force is then applied to the load cell which transmits a signal to the computer-recorder which is indicative of a known maximum force applied condition. An intermediate known force is then applied to the load cell which transmits a signal to the computer-recorder which is indicative of a known intermediate force applied condition. The computer-recorder uses the three signals to establish a load slope for use in the force measuring apparatus.
