  • Page 11: 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 12 An internal rechargeable battery is available which allows the Indicator to be conveniently independent of any external power supply. • Model 703 can be connected to a TRU-TEST printer to print results or to a computer for TRU-TEST storing and further processing data.

    230 or 115 volts AC to 13.8 volts DC at 600mA. (NOT suitable if a 12V printer is connected). Use only the power cable supplied by . Plug it TRU-TEST in to the socket marked 12V DC on the Indicator and tighten the retaining collar by hand only. Calibration The Indicator automatically identifies and calibrates itself to the Loadbars connected to it.

  • Page 16: Operation

    Operation Operation Operation Operating the Model 703 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. Keypad The Indicator comes ready to use with default options set by the factory.

  • Page 25: Zeroing

    Zeroing Zeroing Zeroing To compensate for any build up of dirt on the weighing platform, the Model 703 has three methods of TRU-TEST zeroing the scale: • Power Up Zero • Automatic Zero • Manual Zero Power Up Zero The scale normally zeroes itself on power up, i.e. when it is turned On.

  • Page 26: Automatic Zero

    Zeroing Automatic Zero Model 703 normally re-zeroes automatically TRU-TEST when a load is taken off. However, this feature can be changed. The options are: "Off" Automatic zeroing disabled. "On" Automatic zeroing occurs when the Gross weight is near zero. "On Net" Automatic zeroing occurs when the Net weight is near zero.

  • Page 27: Manual Zero

    Zeroing • Weights more than 2% (of capacity) from the span calibrated zero may show "ZEro oL" (zero overload). • Automatic zero tracking on Net weight maybe disabled. (See Weights And Measures Versions on page 126). Manual Zero If Automatic Zeroing is Off, the scale should be manually zeroed occasionally.

  • Page 28: Taring

    Taring Taring subtracts the container weight so that the display reads a Net weight. The Model 703 can automatically Tare TRU-TEST an empty container which is placed on the scale, or you can enter the container weight using the keyboard (see Setting a Tare on page 21).

  • Page 29: Setting A Tare

    Taring When a tared container is removed from the Loadbars, the display shows the negative of the container's weight: To display Gross weight, the Tare must be cleared (see Clearing A Tare on page 22). If the Power Up Zero function is Off, then any Tare or Set Tare is retained even when the Indicator is switched Off.

Clearing a Tare To clear a Tare: • Press Note: clearing the Tare does not zero the scale. Example use of Tare and Zero Taring and zeroing are useful in situations such as produce weighing, for example weighing potatoes in bins.

    Refer all servicing matters to your Service Centre. The case is a sealed unit TRU-TEST and, if opened, moisture could affect the operation of the Indicator. The product warranty becomes void if the case seal is broken.
  • Page 105 The charger only restarts once the external power supply has been disconnected or turned Off and then reapplied. Model 703 enables the user to read the voltage at TRU-TEST any time in order to check the condition of the internal battery, see Setup Mode on page 13.
  • Page 106 Care and Maintenance A fully charged internal battery reads 12.5 volts or more when Model 703 has been On for 5 to 10 minutes with TRU-TEST no Loadbars or external power source connected. The internal battery is considered low when the voltage reads less than 11.0 volts.

    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 108 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.

Solution Clean with methylated spirits or ethyl alcohol and dry out the Indicator and Loadbar plugs. Cause Loadbar cable damaged.
  • Page 110 Troubleshooting "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 113 Troubleshooting "Pr Fault" displayed Cause The processor inside the Indicator has "crashed", probably due to an electrical trauma in the power supply line. Solution Turn the Indicator Off and then On. If there is a "Bad Conf", "Cal Lost" or "SPC Lost" message during turn On then the crash has caused the loss of vital internal data which the Indicator has been unable to recover by itself.

  • Page 120: Technical Information

    Technical Information Technical Information Technical Information Communications Port Model 703 is equipped with an RS232C serial TRU-TEST interface port for connection to a computer or printer. The Indicator is configured as a DTE (Data Terminal Equipment) device and therefore requires a cross-wired cable for most computers which are also DTE devices.
  • Page 121 Technical Information For connection to a computer or printer using software ("Hon- HoFF" selected), only TX, RX and SG need to be wired. TX and RX usually must be cross wired. For connection to a printer using hardwired (or sometimes called DTR) handshaking, only TX, DSR and SG need to be wired.

  • Page 122: Downloading To A Computer

    Technical Information Downloading to a Computer Model 703 has the facility to download the TRU-TEST records in its memory to a computer. This allows tag (ID) numbers, condition codes (or group counts) and weights to be saved on the computer and used for further farm management purposes.

  • Page 123: Remote Control By Computer

    The following gives details for those writing their own software to control the Indicator. Remote control of the Indicator is gained by sending a STX (02Hex) or a SOH (01Hex) to the Model 703. STX temporarily sets the Indicator to 9600 baud and Xon-Xoff.
  • Page 124 The output consists of a single character: 0, L, C, H which mean zero, low, centre or high respectively. Beep. Activates the Model 703 beeper. TRU-TEST Remote keys 42, 43, 45 & 46 control output modes which are mutually exclusive. The output mode activated remains active when computer control is relinquished and over Indicator power downs.
  • Page 125 Technical Information Remote keys 42, 43, 45 & 46 can be executed from the Indicator's keyboard if necessary. This allows the Indicator to talk to some unintelligent output devices. To do this, turn the Indicator Off and then hold down the '0' key while turning it back On.

The contents of the LCD display then follow as ASCII characters, including any decimal points, commas or colons in their respective positions. Leading or trailing spaces are not removed, so the number of characters is always at least 8.
  • Page 127 Technical Information eg. for 110 baud, wait 200mS. Discard any characters received except ACK. Start at 9600 baud and work down to avoid the Indicator getting junk characters. After determining the baud rate, send an STX (this will temporarily set the Indicator to 9600 baud and Xon-Xoff). Wait until all characters have been sent and then change the computer to 9600 baud, Xon-Xoff.

    If another make of printer is used, or for some reason the factory settings have been changed, the required details are described in Non Tru-Test Printers below. The Indicator's factory default baud (data transfer) rate is 9600 and the handshaking method is "Hon-Hoff" to suit the printer.
