Hi Team,

I have just hacked a bathroom scale and pluged the wires straight from the load cells to the combination board section on the openscale, plugged it in to my computer and opened arduino IDE and a serial monitor. I zero'd the scale then went to calibrate but the values it is outputting are negatives, the scale reacts how you would expect but has a negative sign before the number. I also had to use quite a high calibration factor to get it reading the right (althought negative) value... the calibration factor was around 24000 which took a long time to get there.

Any help would be greatly appreciated.
