Tare Function

There are two ways to re-zero the Ariva scale:
Power-up Zero
The scale will automatically capture zero when it is turned on. The power-up zero capture range is
between -2% and +18% of the scale capacity. When the scale is turned on with a weight on the
platter of more than +18% of capacity, the scale will not capture zero (the weight display will

show " "). After removing the excess weight, the scale will capture "zero" and be ready for
use.
Likewise, if the scale is turned on without its platter, for example, then the scale will be
underweight and will not be able to capture zero.
Pushbutton Zero
The Zero button re-zeros the scale over a range of +/-2% of the scale capacity. To use this
function, the scale must be in the gross weighing mode (NET cursor must be off) and in a non-
motion condition. When the weight on the platter is more than +/-2% of the scale capacity,
depressing the zero key will not be accepted.
Button Tare
The Tare button subtracts the weight of items like packaging or wrapping material.
1. Place an empty container or wrapping material on the platter.
2. Press the Tare button.
3. The "NET" and "T" indicators will illuminate, the tare display will show the tare weight, and the
weight display will show net zero weight.
4. Place the item to be weighed in the container or on the wrapping material on the platter. The
scale will show the net weight of the item.
Preset Tare
If the weight of a packaging material is known, a preset tare value can be sent automatically from
the POS system through the serial connection, as associated with the PLU for that item.
The preset tare will be deleted once the weighing transaction is completed and the item to be
weighed is removed. While a preset tare is active the "NET" and "PT" indicators will illuminate and
the tare display will show the preset tare.
Note: Only one tare method can be used at the same time. If a button tare is active, a preset tare
sent by the POS system will not be accepted. And button tare is not accepted if a preset tare is
active.
