Detector Grid

The Digital Detector grid is integrated with a holder that fits the detector exactly. The grid fits over the
detector handle and has raised edges to fit around the detector. Once together, you may handle the grid
and detector as one unit.
The arrows on the grid surface show the direction of the grid lines, which run horizontally.

Item
1 Grid (6:1 grid ratio horizontal is standard, 8:1 grid ratio horizontal is optional)
2 Detector
The detector automatically detects when the grid is properly in place. If the grid has been improperly
placed on the back of the detector, the detector will not function. The detector reports to the system
when the grid is attached to or detached from the detector.

Grid Attachment

The bottom edge of the detector should be placed into the bottom lip of the grid holder while held in the
vertical position with the carbon graphite cover (on the front of the detector) facing the inside of the grid
holder. Then press the detector into the top edge of the grid holder. Be careful to not pinch your fingers or
clothing when assembling.
While in use, keep a firm grasp on both the grid holder and the detector. The markings for the active area
are clearly shown on the exterior surface of the grid holder.

Grid Handling

The grid is a sensitive device containing delicate mechanical structures. It is made of very thin pieces of
lead (Pb) and interspersed with Aluminum (Al).
