Abstract :
Since low capacity or stainless steel load cells are subject to larger creep errors than medium or high capacity aluminum load cells, the conventional analog compensation method cannot fully cancel out the errors. In particular, the rate of change with creep is high immediately after load application or removal. While OIML R 60 has no stipulation regarding changes in creep immediately after load application or removal, it is important and useful for automatic and non-automatic weighing scales to compensate so as to minimize the creep error during those periods of time. We have developed an accurate compensation method for creep error that occurs immediately after load application or removal on load cells.
