Random Weight PLU’s with Proportional Tare
☛
Some items require two tare values - Fixed Tare and Proportional Tare. Fixed Tare is the weight of the packing material for which the customer does not pay. Typically, this is a tray or sack. On the other hand, Proportional Tare is the percentage of the total product weight that is the “wrapper” for the individual item. This value represents the proportion of tare material in comparison with the gross weight of the item (commodity).
A good example of an item that uses this tare configuration would be individually wrapped candy. If the Proportional Tare value for a specific individually wrapped type of candy is 14%, it means that for a gross weight of 1 pound, the total weight of individual wrappers is .14 pounds.
On the screen, you will notice these values represented as Tare and Total Tare. When you place the item on the scale for weighing, the Total Tare value changes to reflect the calculation of Proportional Tare. The Total Tare value is the sum of the Fixed Tare and Proportional Tare values.
Note
For a more detailed explanation of Proportional Tare (Percentage Tare), refer to the Appendix.
