Load Cell Exclusion (for dependent channel systems)
11© Rice Lake Weighing Systems •All Rights Reserved
15.Load Cell Exclusion (for dependent channel systems)
No channel excluded.
Channel 1 excluded.
Channel 2 excluded.
Channel 3 excluded.
Channel 4 excluded.
If a load cell is broken, it’s possible to temporarily 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.
Visible only in DEP.Ch mode.
16. Weight Filter
The active weight filter is displayed, alternating with the weight value.
Press and keys to scroll through the available filters (from slowest to fastest, F1 to F10).
17. Unbalancing
Visible only in DEP.Ch mode.
The instrument has an active unbalance function as standard that signals if the load is unevenly distributed, compared to the
condition saved via step STR.UNB.
Imbalance occurs when the load distribution percentage value on a cell deviates by at least 10% for more than 3 seconds.
