So every figure carries the part's 1 % tolerance as an assumed gain uncertainty, whether the meter reports q=uncal (nominal never declared) or q=cal (nominal declared with CAL SHUNT, accepted by the owner on 2026-10-28). It is 1 % of an absolute level and 1 % of a difference: a gain error never cancels in a subtraction, only the offset does. The offset's residual on an absolute reading is about +-0.5 uA, and range 0's 3.125 uA quantum adds up to +-1.56 uA of bias on a very quiet level.",
