  • Thank you for this comment. I'd been staring at the wheatstone bridge arrangement for a while and utterly failing to comprehend it — thinking along the lines of "if all four sides of the bridge simultaneously drop in impedance because the weight is balanced across all the strain gauges, surely the resulting 'sense' voltage remains precisely the same?". With your comment, the penny finally dropped. I don't know if I was just being particularly stupid today, or the documentation elsewhere could do with being a little clearer :)

No public wish lists :(
