About This Manual
This manual tells you how to operate the TRU-TEST Model 700
Indicator - the keyboard and display unit for the TRU-TEST 700
Series agricultural weighing system.
Models 701, 702 and 703 are more advanced Indicators which
are described in separate manuals.
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 30 before
contacting your TRU-TEST Service Centre.
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 / display unit) and one or more Loadbars or
Suspension Cells. The Loadbars are fitted beneath a platform
or crate that holds the animal, and the 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 statistics can be recorded for later analysis.
In the more advanced Models, 702 and 703, weight data is
recorded and retained in the Indicators memory and can be
output to a printer at any stage during or after weighing.
Comprehensive reports including weights, tag numbers,
condition codes and statistics can be printed. The data can be
directly transferred to a computer via a cable for permanent
storage and further analysis.
Calibration
On power up, the Indicator automatically identifies and
calibrates itself to the Loadbars connected to it. The latest
Indicators operate with the complete range of TRU-TEST
Loadbars, Suspension Cells or Produce Platforms. This is
known as Standard Calibration.
There is no need for the operator to calibrate the Indicator when
starting up or even when swapping from one set of TRU-TEST
Loadbars to another. Standard Calibration eliminates the need
for time consuming calibration using test weights.

System Overview
Applications using other manufacturers' Loadbars, which are
not pre-programmed, can be satisfied using Span Calibration
with known test weights.
Indicator Options
•An internal rechargeable battery is available which
allows the Indicator to be conveniently independent of
any external power supply.
•The two more advanced models (702 and 703) can be
connected to a TRU-TEST 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.
•For livestock weighing, animal movement can sometimes
be a problem with a digital scale. The Indicator
eliminates this 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.
