  • Page 5: About This Manual

    About This Manual About This Manual About This Manual This manual tells you how to operate the Model 700 TRU-TEST Indicator - the keyboard and display unit for the TRU-TEST Series agricultural weighing system. Models 701, 702 and 703 are more advanced Indicators which are described in separate manuals.

  • Page 7: System Overview

    System Overview System Overview System Overview 700 Series is an advanced and versatile TRU-TEST 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.
  • Page 8 • The two more advanced models (702 and 703) can be printer to print results, or to a connected to a TRU-TEST computer for storing and further processing data. Reliability • Indicator is a rugged and robust product...
  • Page 9 System Overview Main Features • LIVE Weighing Mode. • Provides STATISTICS on recorded data. • FLEECE (FINE WEIGHT) Mode for better precision at low weights. • ZERO controls. • Span Calibration using known weights if required.

  • Page 10: Installation

    When you unpack your new Indicator, complete and post the warranty card to ensure you receive the service you are entitled 700 Series System Unpack and install the Indicator mounting stirrup in a convenient position. Ensure that it is located securely.
  • Page 11 Installation Install the Loadbars or Suspension Cells according to the manual which comes with them ( Loadbars TRU-TEST Manual). Run the Loadbar cables to the Indicator, making sure they are protected from damage. Unscrew the protection caps from the cable plugs and the Indicator sockets marked CELL1 and CELL2.

  • Page 12: Calibration

    Installation Calibration The Indicator automatically identifies and calibrates itself to the Loadbars connected to it. This is known as Standard Calibration. Span Calibration with known weights can also be carried out. (See your Service Centre). TRU-TEST...

  • Page 13: Operation

    Operation Operation Operation Operating the Model 700 is straightforward and TRU-TEST logical. Many functions are performed with a single key press. Safety To avoid damage, never load the scale further if the overload message appears on the display.

  • Page 14: Keypad

    0.5kg or 1.0kg division size. The division size close to zero (base resolution) depends on the Loadbars fitted. (See your Loadbars Manual.) TRU-TEST The division size automatically changes at particular weight limits to reflect the accuracy of the scale. (See Autoranging on page 38.)

  • Page 15: Switching On

    Operation Switching On If there is no internal battery, connect the 12 volt supply, red lead to the positive terminal, black to negative. Press . Display shows: The scale zeroes itself automatically (if Power Up Zero is On, see page Current weight: Weighing Normally the display shows the current live weight on the...

  • Page 16: Switching Off

    Press Disconnect the power supply if required. Automatic Power Off Model 700 automatically switches Off after TRU-TEST 30 minutes if no change in weight or key press is detected. This conserves battery life when the scale is not being used.
  • Page 17 Operation • To change the units, press...

  • Page 18: Zeroing

    Zeroing Zeroing Zeroing Model 700 has three methods of zeroing the TRU-TEST scale: • Power Up Zero • Automatic Zero • Manual Zero Power Up Zero The scale normally zeroes itself on power up, ie. when it is turned On. The weight of the platform or crate on the Loadbars is zeroed.

  • Page 19: Manual Zero

    Zeroing To change the Automatic Zero setting (On or Off): • Press The new setting is displayed for about 1 second. If Automatic Zeroing is On, Manual Zeroing is usually unnecessary, unless the weight being zeroed is relatively large and is outside the range for Automatic Zeroing (6 divisions maximum).

  • Page 20: Recording Statistics

    Recording Statistics Recording Statistics Recording Statistics Model 700 has the ability to record and display TRU-TEST statistics during the weighing session. Ensure that previous statistics are cleared before starting a weighing session (see Clearing Statistics on page 18). As each animal moves onto the platform: Wait for the Stable pointer to come on.

  • Page 21: Viewing Statistics

    Recording Statistics Viewing Statistics To view the statistics, press The following information is displayed in sequence as you keep pressing the key. COUNT Number of animals weighed. TOTAL Sum of all the weights of all the animals weighed. AVERAGE Average weight of all the animals weighed.

  • Page 30: Care And Maintenance

    Care and Maintenance Care and Maintenance Care and Maintenance Model 700 Indicator is a rugged and robust TRU-TEST 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.

  • Page 31: Internal Battery

    Refer all servicing matters to your Service Centre. The case is a sealed TRU-TEST unit and, if opened, moisture could affect the operation of the Indicator. The product warranty becomes void if the case seal is broken.

  • Page 32: Internal Battery Charging

    The internal battery charger operates from either the recommended power supply unit or a 12 volt car TRU-TEST battery. Other charging supplies may damage the Indicator resulting in the warranty becoming void. When charging the indicator from a car battery, the car battery will lose energy equivalent to leaving the car headlights on for approximately 1 hour.
  • Page 33 Care and Maintenance • To read the voltage, press Press any other key to return to live weight display. A fully charged internal battery reads 12.5 volts or more when the indicator has been on for 5 to 10 minutes with no Loadbars or external power source connected.

  • Page 34: Troubleshooting

    Troubleshooting Troubleshooting Troubleshooting "8 Volt" displayed Cause The internal 8 volt supply (used to supply the Loadbars) is outside its specified limits. Solution Disconnect the Loadbar cables from the Indicator one at a time. If the "8 voLt" message disappears then there is a fault in the Loadbars or their cables.
  • Page 35 Troubleshooting If the Indicator is not using Span Calibration then it may still be used without its Standard Calibration but with reduced accuracy. The accuracy cannot be guaranteed. Return the Indicator to your Service Centre to have its Standard Calibration data cleared or restored. "CS Fault"...
  • Page 36 Troubleshooting Solution Ensure animal correctly positioned on the platform. "High Bat" displayed Cause The supply voltage is greater than 16 volts DC. This message is displayed for 15 seconds and then the Indicator switches itself Off. Solution Replace power supply with a unit that can provide 10.5 to 16 volts DC.
  • Page 37 Troubleshooting Solution The Indicator can be used without the Loadbars connected for setting up. If the condition persists when the Loadbar cables are plugged in, refer to "bAd codE" above. Cause Old code 99 Loadbars are being used. Solution Contact your Service Centre for reconfiguration of the Indicator to recognise 99 as a valid code.
  • Page 38 Troubleshooting Solution If configured to do so, and if standard Loadbars are being used, the Indicator may continue to function using Standard Calibration although possibly with different resolutions and load ratings and with reduced accuracy. If you need to use Span Calibration, the system must be re-calibrated in situation.
