The load cell can be exchanged by first removing the stainless steel platter. Turn the unit over and remove
the six 8 mm screws (size) from the bottom plate. Separate the top enclosure from the bottom plate.
Remove the two Phillips head screws from the bottom plate. Extract the load cell out by lifting it off of the
bottom plate.
Install the new load cell by placing it over the studs on the bottom plate. Fasten it to the bottom plate with the
two Phillips head screws. Plug the load cell wire connector into J5 header on the main board. Reinstall the
top enclosure.

The load cell can be exchanged by removing two M6 1x 20mm (size) bolts from the bottom plate and two
M6 1 x 16mm (size) bolts from the top spider assembly.
Figure 1-4: Model 675 Load Cell Installation
Install the new load cell by placing it in the load cell cavity. Fasten the load cell by installing the bolts on the
bottom plate. Reinstall the spider assembly. NOTE: When exchanging a load cell with another, the
overload stop and corner overloads must be reset. See Table 1-1 for specifications.
