About This Manual
About This Manual
This manual tells you how to operate the TRU-TEST Model 702
Indicator - the keyboard and display unit for the TRU-TEST
700 Series agricultural weighing system.
The TRU-TEST Model 703 Indicator which is a more advanced
model is described in a separate manual.
Operation of the Indicator is described in the main text of this
manual. Complete lists of keys, display pointers and messages
are given in the Quick Reference Sections at the end.
If you are setting up the system for the first time, read the
Installation section in this manual, also read the TRU-TEST
Loadbars Manual for instructions on installing the loadbars.
To gain the best possible performance from your Indicator and
especially if you have an internal battery installed, read the
Care And Maintenance section.
If problems arise, refer to Troubleshooting on page 61 before
contacting your TRU-TEST Service Centre.
Special versions of the Indicator are made which comply with
the regulations for "trade" use in particular countries.
Differences which may apply are noted at the end of sections
under the heading Weights And Measures Versions and
specifications for particular countries are given in Weights And
Measures Versions on page 85.
In this manual, the term "Loadbar" is used to mean "Loadbar,
Suspension Cell or Produce Platform".

Agricultural Weighing System
System Overview

System Overview
System Overview
The TRU-TEST 700 Series is an advanced and versatile
agricultural weighing system. It has been designed with the
benefit of many years of animal weighing experience and is
used by farm management professionals and agricultural
scientists the world over.
The system consists of a microprocessor controlled Indicator
(keyboard and display unit) and one or more Loadbars or
Suspension Cells. The Loadbars are fitted beneath a platform
or crate and the animal's weight is transmitted from the
Loadbars to the Indicator. The Indicator gives a digital readout
of the weight and, through the keypad, provides control over the
processing capabilities of the scale.
Weight data is recorded in a reliable solid state memory in the
Indicator and can be output to a printer at any stage during or
after weighing. Comprehensive reports including weights, tag
(ID) numbers, condition codes and statistics can be printed.
The data can also be directly downloaded to a computer via a
cable for permanent storage and further analysis.
A computer program, the TRU-TEST AgLinker, is available
from your TRU-TEST Dealer for easy transfer of data between
the Indicator and a PC computer.
Calibration
On power up, the Indicator automatically identifies and
calibrates itself to the Loadbars connected. The latest Indicators
operate (without re-calibration) with the complete range of
TRU-TEST Loadbars, Suspension Cells or Produce Platforms.
This is known as Standard Calibration and eliminates the need
for time consuming calibration using test weights.
System Overview
4
Applications using other manufacturers' Loadbars, which are
not pre-programmed, can be satisfied using Span Calibration
with known test weights.
Indicator Options
•The internal rechargeable battery option allows the
Indicator to be conveniently independent of any external
power supply.
•Models 702 and 703 can be connected to a printer to print
results or to a computer for storing and further processing
data.
Reliability
•The TRU-TEST Indicator is a rugged and robust product
designed to withstand the environment associated with
livestock handling. The case is made from extremely
tough, ultraviolet resistant polycarbonate. The keyboard
is completely sealed for all weather operation.
•The Indicator keeps three copies of calibration data in a
separate battery backed memory so that it can recover
automatically after a power failure or electrical
disturbance.
•The Indicator can be unplugged from the Loadbars and
taken indoors for you to study the data and recharge the
battery.
•For livestock weighing, animal movement can sometimes
be a problem with a digital scale. The Indicator
eliminates the problem using SUPERDAMP©- a
sophisticated statistical damping technique.
•The large digital display is easy to read. Stabilisation of
the display is usually extremely fast - within seconds.
