Absolute error change per °C temperature change is a combination of the gain and offset drift of many

components. The theoretical worst case error of the board may be calculated by summing these component

errors. Worst case error is realized only in the unlikely event that each of the component errors is at their

maximum level, and causing error in the same direction.
