Load cell and no preload

For the load cell to read tension accurately it should be 1) straight and also

2) not be preloaded.

1. To straighten the load cell- The white bolts can be adjusted on each side to center the frame.

2. The two adjustable screws, shown below, protect the load cell from being crushed when the actuator extends to the home position after each treatment. You cannot see the tip of the screw from this angle. When the table is in the home position, you should be able to only slip a piece of paper between the end of the screw and the painted frame. IF paper will not fit then the screws are pressing against the frame. This resistance will be reflected in “Pounds” on the control panel when the treatment begins. IF the gap is too big, the bolts will not push the frame but the actuator will push into the load cell and damage it.
