              To ensure optimum performance of the TWR-1, the internal battery may need to
              be charged for up to 16 hours before first time use.

              Important: If the TWR-1 is to be stored for an extended period, this should be
              in a cool dry place with a fully charged battery.

              1.   Connect the power adapter at the base of the unit and plug the TWR-1 into a
                   power outlet and switch ON.

                   The charging icon will display on the screen.
              2.   When the charge shows 100% the TWR-1 is ready to use with or without the
                   power adapter.

              • When the TWR-1 is in use, the battery icon
                  will display and show remaining charge.
              • When using the scale and the charge level falls below 10% the battery icon
                  will flash with a red outline. You will have about 30 minutes to complete the
                  weighing session before the TWR-1 must be charged.
              • When the charge level becomes critical the unit will shut down.
              •    To check remaining run time at current settings, from the Home screen, go to
                   Settings    > About > Battery.

                                                       Gallagher TWR-1 Weigh Scale Quick Start Guide


          Installing the TWR-1

              The TWR-1 can be placed on a table top or mounted
              on the bracket supplied.

          Installing the Scale bracket
              The bracket can be mounted on a flat vertical surface, a round post, or a rail.

              To mount the bracket on a flat vertical surface, or a round wooden post, use
              the 4 x tek screws included with the unit.

              To mount the bracket on either a vertical or horizontal bar, use the ‘U’ bolts
              included with the unit.

              It is not recommended to mount the TWR-1 bracket on the weighing crate or
              chute as interaction with the scale can impair weighing performance.

Installing the loadbars
    If using loadbars, follow these steps:
    1. Select a weighing site that provides a solid, level and well drained surface.
    2. Ensure the loadbars and platform are well secured and clear of any

    3. Either bolt the loadbars to the concrete pad or locate them on studs set into
          the concrete. It is important that the loadbars and platform sit flat without
          any rocking or twisting to avoid weighing inaccuracies.
          Note: It may be necessary to shim the loadbars or platform to ensure there
          are no twisting pressures within the platform. Weights should be evenly
          distributed over the top of the weigh bars.
    4. Connect the loadbar cables to the base of the TWR-1.
          A beep will sound indicating a successful connection/ disconnection of the

          WARNING – Do not weld the loadbars or any structure that they are
          attached to. Loadbars contain sensitive electronic devices which will be
          damaged by welding. Damage caused by welding will void warranty.

Position the TWR-1:
    •    clear of the platform to ensure it does not interfere with the flow of
         animals during the weighing cycle
    •    within easy reach of the loadbar leads
    •    within easy reach of the operator (for manual weighing)


                                                    Gallagher TWR-1 Weigh Scale Quick Start Guide

          Installing the Antenna Panel
              The TWR-1 has an internal reader, that when connected to a Gallagher Antenna
              panel will capture the Electronic ID tag data.
              To weigh animals in a crush, you will need:

                      • Gallagher Antenna Panel kit
                      • 4m Antenna Extension Cable G05600 or
                           6m Antenna Extension Cable G05602
              Note: A short adapter cable G05601 may be required on early versions of the
              Sheep Auto Drafter made prior to 2018.
              To mount your Antenna panel, refer to the instructions included with the panel.

              Important: Use the defined mounting holes, because drilling through the

Gallagher TWR-1 Weigh Scale Quick Start Guide

     When you gather information about an animal, it is recorded in a Session. Each
     event such as weighing, adds a record to the current session.

     A template using pre-determined defaults can be set up and used each time you
     start a new session.
     Note: It is recommended a new session is opened for a new day’s activity or for
     a new group of animals. An animal cannot appear within the same session more
     than once.
     To start a new weighing session:
     1.   From the Home screen, tap New.             The New Session screen is
     2.   Tap Quick Start to open the Weigh screen with the scale default settings.
          Note: To set up and use templates, refer to the TWR-1 On-board Help.

          Note: Before weighing, 0.0 should be displayed. If not, press         .

    3.    Load the animal onto the platform.
    4.    If using the internal reader, the animal’s Electronic ID will be scanned, or you
          can scan with a hand-held reader and record the animal’s Visual Tag Number.
          Note: The internal reader will only read a tag when loadbars are connected
          and weight is detected on the weighing platform.
    5.    If weighing in AUTO - Automatic weight lock, the scale will lock on to the
          weight and hold it on the screen until the animal leaves the platform.
          If weighing in MAN - Manual weight lock, you must first press Weigh          .
          When the weight becomes stable, it will lock.
    6.    Move the animal off the platform.

    Important: If the weight displayed does not always return to 0.0 after weighing,
    check for dirt or manure that may have been left on the platform.
    The TWR-1 can be re-zeroed by pressing        .

                                                        Gallagher TWR-1 Weigh Scale Quick Start Guide

               • When the weight locks, there will be a beep (if turned on in Settings) and a red
                   light above the Weigh button displays briefly.
               •   Other information, for example: Notes, can be entered once the weight has

               •   In either mode, you can re-weigh an animal by pressing Weigh           after a
                   successful weight lock.
               •   If drafting is turned on, the gate number and group will display, in top right
                   corner of the screen, indicating the drafting category. Tap this box to override
                   the drafting decision.
               •   By default the scale will automatically zero any debris left on the platform
