2.4.9 Totalization
Knowing how many weighing transactions were performed and how much material was processed during a
particular period of time is useful information for many weighing applications.
The T72XW indicator provides both grand total (GT) and subtotal (ST) registers and counters. Counters have a
limit of 1,500,000 and registers will accumulate up to 11 digits of weight, including any digits to the right of the
decimal point. For example, a scale programmed for 500 x 0.1 kg will accumulate weight values up to
9999999999.9 (11 total digits). If either of these limits is exceeded, an error message will display and the totals
must be reset before additional weights or counts will be added.
2.4.10 Alibi Memory
The Alibi Memory stores transaction data that can be retrieved in order to verify transaction information.
Information stored in the Alibi Memory includes:

Transaction counter value

Date and time of transaction

Gross, net, and tare weights including units of measure

If the T72XW indicator
has been programmed as “approved”, Alibi Memory enabling or disabling is only
accessible if the security switch (SW1-1) is in the OFF position.
2.5 Applications
Each of the five applications is accessed by pressing the FUNCTION key . When this key is pressed, the
indicator will leave normal weighing mode and enter whichever application mode is selected in setup at Application
> Function Key > Assignment. Press the
FUNCTION key again to return to normal weighing mode.
Chapters 3 through 7 detail the operation of each application. Appendices D include setup steps required to
prepare for operation in each application.
2.5.1 Animal/Dynamic Weighing
The Animal/Dynamic Weighing application provides the ability to calculate and display an average weight value
over a user-defined sampling time period. This is useful when the weight data is constantly unstable as in the case
of weighing live animals such as livestock or lab animals. The application provides the following:

Simple, one key operation

Prompts for start of weighing cycle

Weight averaged over variable sampling time period

Display of remaining time in cycle

Final average weight display and print

2.5.2 Checkweighing
The Checkweigh application provides the ability to compare weight on the scale to a stored target weight, while
indicating a comparison status. Three zones are supported in the
– Under, OK and Over.
The T72XW display indicates the Over/Under status graphically. Three discrete outputs can be configured for
control of external lights, or a similar device, to indicate the current status of the weight comparison.
