Scaling-Factor

[ahmed-asn]

I put a 2500gr mass on my Weight-Scale and get -425gr, so i think the Scaling-Factor isnt correct. i test my Weight-Scale with Arduino and its works fine, so the hardware doesnt have problems. Is there an Forumla to calculate the Scaling-Factor, or is there another Problem with the Code?

Thanks a lot

The SCALING_FACTOR property of the HX711 object could be adjusted to change the scaling factor, although I would find it strange that your device is wired up such that adding weight lowers the perceived weight of the IC. Did you tare() the empty scale before applying the weight?
