The zero offset error will produce a systematic error in the ammeteruq,xub*zdho/yw:) b 4.o(pcc readings. A large systematic error results in measurements which are not accurate, in other words far from the correct value. Precision refers to how reprou,.z:d * h x)cqcp ybub4/wo(oducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
