    Hi All, The loadcell has been calibrated with 4 points (5, 20,50,100 grams) , zero acquired, calibration saved. Motion band has been set (LC Motion Band = 2) The auto-zero-tracking is set to pretty tight definitions: LC time = 1, LC tracking band = 1, tracking range = 1, and activated. Everything works fine for some time - the loadcell output is pretty steady on zero, some minor fluctuations here and there but it seems that the zero correction fires every now and then to correct. However, in a matter of hours, zero begins to drift ( up to some 18 grams), which makes the whole application null and void. Same happens in both excitation modes, btw - in DC mode zero drifts up (+), in AC mode zero drifts down (-). Theres no litter buildup on the platform, no significant temperature fluctuation around the loadcell, not much mechanical movement - the construction is quite solid. What am I missing here ?
