6.1.3.5 Tare
Tare can be taken on an item two ways: Automatic or digital.
REMOTE TARE
The unknown weight of an object can be tared-off automatically by placing the object on the scale
platter, then with the display in a stable non-motion and positive weight condition, sending an
uppercase ASCII T character followed by
C
R
from the host will automatically subtract the weight.
The tare function must be enabled. Chain tare is not permitted. A display triangle, located under the
least significant weight digit on the scale display will illuminate to indicate net weight is displayed.
Negative weight will cause dashes to be displayed and status byte will be sent to the host instead
of weight data.
DIGITAL TARE
Keyboard tare is set in the scale when an uppercase ASCII T character, followed by five ASCII
digits and a CR is sent by the host. The scale weight display must be positive and stable. The tare
value input is limited to the scale capacity. In metric mode, the tare value must always end in 0 or
5.
CLEARING TARE
If auto tare clear is enabled, tare is automatically cleared whenever the scale returns to gross zero
after having indicated a stable net weight at least one increment above net zero. If auto tare clear
is disabled, tare can be cleared by sending an uppercase ASCII C from the host.
