Calibration does not work for all weights #202

JoeToeniskoetter commented 3 years ago

Hello,

Hoping someone else has run into this issue. After calibrating my scale ( 4 50kg cells) , the scale is only accurate around the weight I calibrated with. For instance, I calibrate with 180lbs, then put 165 lbs on the scale, the scale only reads 18 lbs. If I put 185 lbs on the scale the scale reads closer to correct.

Does anyone have an idea what could cause this?

Thanks

Are you sure you gave 2 points measurement to calibrate your scale ?

Usually we give the zero and a known weight.
