It is common to add external zero trim adjustment on load cells. The span ajust is one or two resistors on the excitation. When two are used they are installed with one on the plus & minus excitation leads to keep the bridge symetrical and reduce cell interaction when used in multi-cell applications..
In reality there are two camps on bridge span trimming - they sceond school of thought is to put a variable resistor between signal leads and sprinkle isolation resistors around the bridge if used in multi-cell applications.
The company says it anticipates high-definition video for home security and other uses will be the next mature technology integrated into the IoT domain, hence the introduction of its MatrixCam devkit.
