Operations

Weighing and Communication

Place the item to be weighed on the platter, the weight will be displayed.
Remote ASCII commands can control all other functions including data transfer, zero, and tare,
depending on the protocol.

Backlight function

Viva is equipped with a backlight for the display. To switch on the backlight, Press and hold the
"ZERO" key until a longer beep is heard. Use the same procedure to switch the backlight off or just
switch the scale off by the power switch.

Re-zero function

There are two ways to re-zero the scale:
1. Power-up Zero
2. Push button Zero
Power-up Zero
The scale will automatically capture zero when it is turned on. The power-up zero capture range
is +/-10% of the scale capacity. When the scale is turned on with a weight on the platter of
more than +/-10% of the capacity, the scale will not capture zero (the weight display will show
"-----") and the scale will not be ready for use. After removing the weight the scale will capture
"zero".
Pushbutton Zero
The ZERO key 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.
capacity, the depression of the zero key will not be accepted.

Tare Function

The Tare key allows you to subtract the weight of items like packaging or wrapping material.
1. Place an empty container or wrapping material on the platter.
2. Press the Tare key.
3. Place the item to be weighed in the container or on the wrapping material and onto the
platter.
Note: A Tare command can be sent from a POS through the Viva's serial connection. Whatever
method is used to start a transaction must continue to be used until the transaction is over. If the
pushbutton is used first, a remote tare command will not work. Conversely, if a remote tare is used
then the push button will not work until the transaction is complete and the scale has returned to
zero.
