  • Page 10: Unpacking The Instrument

    OPERATOR’S MANUAL UNPACKING THE INSTRUMENT DISENGAGE SHIPPING BRACE The shipping brace must be moved to the operate position before applying power. Since the grain test cell cycles through an unload sequence during power up, damage may occur with the shipping brace in the transport position.

  • Page 11: Instrument Placement

    OPERATOR’S MANUAL Rotate the brace back into supporting position before moving or shipping the unit. If the cell is not adequately supported operating performance may be adversely affected due to cell bouncing. Some effort is required to move the brace back into position. It may be helpful to reach inside the drawer front and lift up on the cell while attempting to lock the brace into the transport position.
  • Page 12 OPERATOR’S MANUAL To Level the Instrument: 1. Use the self-contained level on the panel top to position the GAC 2100 on a flat level or nearly level surface. 2. Adjust the four rubber foot pads to level and stabilize the unit (Figure 5).
