Press the
TARE
key to tare the scale. The weight that was displayed is stored as the tare
value and that value is subtracted from the display, leaving zero on the play. The "NET"
indicator will be on. As product is added only the weight of the product will be shown. The
scale could be tared a second time if another type of product was to be added to the first one.
