Tare
Tare is used to subtract the weight of an empty container from the gross weight on the scale to determine the net
weight of the contents. Tare is inhibited if the scale is in motion.
Three setup screens are available to configure tare:
Tare Types Auto Tare Auto Clear
Tare Types
Use the Tare Types setup screen to enable or disable pushbutton tare, keyboard tare, and net sign correction.
Pushbutton Tare
When pushbutton tare is Enabled, the TARE scale function key can be pressed when an empty container is
on the scale to determine tare. The indicator displays a zero weight and net mode. When the container is loaded
and placed back on the scale, the indicator displays the net weight of the contents.

If Pushbutton Tare is Disabled, execution of a remote Tare is still possible via SICS or CPTZ commands or
from discrete input command.
Keyboard Tare
When keyboard tare is Enabled, the known value for the empty weight of a container (tare) can be entered
manually. The indicator will then display the net weight of the contents of the container. Keyboard tares are
automatically rounded to the closest display division.
Net Sign Correction
Net sign correction enables the T72XW indicator to be used for both shipping (inbound empty) and receiving
(inbound loaded) operations. If net sign correction is Disabled, the indicator will display and print a negative net
weight when the tare weight is larger than the gross weight. If net sign correction is Enabled, the indicator will
switch the gross and tare weight fields on the printed ticket, if necessary, so that the larger weight is the gross
weight, the smaller weight is the tare weight, and the difference is always a positive net weight. Net sign correction
affects the printed data output and the displayed weight. Continuous data output will continue to show a negative
net weight value.
Net sign correction will operate with pushbutton tare and preset tare. An example of weight values with and without
net sign correction is shown in Table 3-1. In this example, the tare register value is 53 kg and the live weight on the
scale is 16 kg.


When net sign
correction is enabled, the tare weight field in the recall display will be labeled with the letter “M”
to indicate “Memory” instead of “T” or “PT”.
Auto Tare
Use the Auto Tare screen to enable or disable automatic tare, to set the tare and reset threshold weights, and
enable or disable motion check.
Auto Tare
When auto tare is Enabled, the tare weight is taken automatically when a container above the threshold weight is
on the scale and settles to no-motion. Set to Disable if automatic tare will not be used.
