ABSTRACT:
Weighing apparatus including a stability display indicator (SA) arranged adjacent the load read-out display (RA) for indicating when the movement of the load-receiving member relative to the housing has diminished to a quasi-stable condition within a given tolerance range, thereby to shorten the time required to perform one or more weighing operations. An automatic standstill detector (ASD) contains a control system which, upon change of a tolerance range display, for example, by darkening or illuminating individual indicators matched up with the tolerance ranges, signals the moment at which the load receiving member achieves a given quasi-stable standstill condition.
