Linearity Errors
Linearity is a scale’s ability to maintain a consistent counts-to-load ratio (a straight line
on the graph). When there is a linearity error, a scale reads correctly at zero and at full
load capacity but incorrectly in between those two points (see Figure 3-3). The weight
indication can either drift upward and read higher than the actual weight (as shown in
the graph) or drift downward and read lower than the actual weight.
