By changing the re-zero execution conditions, it is possible to change the time until re-zero is performed, and to execute re-zero even in an unstable state.
  • Page 42 (4) Averaging range Averaging starts when the change in the weighing data is within the "variation range". When the averaging width is large, such as when filling a very small amount, the response may be slow because the averaging range is not exceeded. In that case, reducing the averaging range can speed up the response at very small amounts.
