15. Broken load cell exclusion (for dependent channel systems) If a load cell is broken, it’s possible to temporarely exclude the channel where it is connected and continue to weigh, pending replacement. WARNING: this operation reduces the accuracy of the weighing system. We recommend use for liquid weighing or in applications where the load is evenly distributed.
