Mode change (EL3356-0010 only)
In particular for dynamic weighing procedures it may make sense to considerably change the measuring
characteristic during the weighing procedure. For example, if a bulk material is filled by the sack within
5 seconds, a very open filter should initially be used so that the measured value quickly follows the fill level.
During this phase it is of no importance that the measured value is very inaccurate and subject to high
fluctuations. If the sack is >90 % full, filling must be slowed down and the loading must be followed with
higher accuracy; the filter must be closed. Therefore the two conversion modes can be switched via the
process data bit "Sample mode" in the EL3356-0010 and in the EP3356-0022 in relation to the processing of
the analog values.
The mode change takes about 30 ms, during which time the measured values are invalid and indicate this by
the status byte.
