Dismount the cell from the bracket by removing the four securing

screws (two on top, two on the bottom) using a 9/64 in. Allen

wrench. Place the measurement cell on a clean, flat surface with the

pressure sensor facing up. Refer to Figure B–5 below.

Orient the measurement cell to avoid any debris from entering the

cell.
