Okay, ignore my last comment. I have looked at your calculation sheet, and at the installation instructions for the transducer.
The transducer is rated for only 500 microstrain.
If you load it to 705 microstrain, it will be permanently damaged, i.e. both the zero and the span will probably change, or maybe one of the elements will break.
I'm guessing that's why you put the 5mm step in the bar, but then you have to use the section dimensions at the transducer location to recalculate the transducer response. Off the top of my head, the resulting asymmetry makes me unconfortable, but it may be ok; check with HBM.
You should get a signal from the transducer when you apply the force at the end of the cantilever beam. If the force is applied at a corner as shown, not the center of the appropriate edge, the transducer output may be misleading because of the twisting moment on the beam, for which I don't think the transducer will compensate.
The transducer is optimized and compensated for steel beams. On an aluminum beam, the zero is going to drift with temperature, probably enough to bother whatever you are trying to do.
Again, please call HBM.
