ZERO Sets the display to zero, programmable: 2% or 100% of capacity.
Section 4: User Operations 4.2. OPERATING PROCEDURES • The Zero, Tare and the AZT functions require the displayed weight to be stable before these functions will operate. • The weight reading is stable if the variation in weight is less than the programmed MOTION BAND. 4.3. GROSS, TARE AND NET Weight NET There are three terms used when weighing an object’s or load’s amount. The NET WEIGHT (product only) is the GROSS WEIGHT (total amount) minus the TARE WEIGHT (container only).
