The Mark-10 ESM303-003 Safety Shield for ESM303 Test Stand is used to provide pinch and sample debris protection for the operator. The shield is constructed of rugged PETG material. It rotates via ultra-smooth bearings in both the clockwise and counter-clockwise directions, guided into the open or closed positions with magnetic detents. An electrical interlock prevents test stand operation while the door is open. For crosshead adjustment during sample loading, the FollowMe force-based positioning function is active even while the door is open. The FollowMe function is included with the shield, and does not need to be separately ordered with the test stand.
