Tare always 8388607 weight nan

[dawidwekwejt]

First time I connected C to WHITE, + to RED and - to BLACK. With this I got always 0 weight, so I changed wiring: C to RED, + to WHITE and - to BLACK. After that I had tared scale and calibrate it with 1L botle. In calibration mode I set 1.000000000000. Why no I got nan value?
