Setting Nominal Width, Upper and Lower Limits for Multiple Web Width Measurement

In this episode of the Multiple Web Width Measurement Application Series, we demonstrate how to set nominal width, upper limit, and lower limit parameters for web width measurements on the SCU6x Controller. Learn how to adjust increments, set alarm and warning limits, and configure digital outputs to monitor width variations effectively. Whether you're manually setting up or automating through Ethernet, this guide provides a comprehensive walkthrough for optimizing your web handling processes.
