table below.
Field Function
ADUError AD conversion error (OR function of bits E1, E3, E7).
AboveMax The weight value has exceeded the Max (FSD), but is still
within Max + permissible overload (gross ≤Max + over
load).
Overload The weight value has exceeded the measuring range. No
valid weight data is specified (gross >Max + overload);
ERR2.
BelowZero The weight value is negative (gross < 0d).
CenterZero The weight value is within center zero (0 ± 0.25 d)
