A tare weight is the weight of an item’s packaging that must be deducted from the total weight of the item before the retail price is calculated. For example, the price of the container is deducted from the weight of a salad sold by the gram before the price is calculated.

You assign tare weights to individual PLUs on the PLU window, or to departments on the Department window. The unit of measurement that is used at the POS terminal to interpret the weight is defined in the setup of your scale hardware.

For example, assume you define a tare weight to be 5 and you assign it to PLU 457975276 (salad). If your scale uses grams as its unit of measurement, then 5 grams are deducted from the weight of PLU 457975276.
