In an SR test, how much should the position of rest of the two opposite moving balance indicators change by at least?

In an SR (Static Rebalance) test, the position of rest for two opposite moving balance indicators is a critical aspect that ensures the precision of the weighing system. The requirement for the change of these indicators is set to a minimum of 0.04 inches. This value is significant because it establishes a tolerable range for the measurements provided by the balance.

A shift of at least 0.04 inches indicates that the balance is sensitive to external factors and can register slight changes in weight accurately. The aim of this specification is to ensure that the balance can perform reliably under varying conditions, which is essential for securing valid and dependable measurement results in weight verification practices. Thus, the stipulation for a minimum change of 0.04 inches in the resting position of the balance indicators is essential for confirming the proper functioning of the weighing system.
