The zero offset error will produce a systematic er mz b66wl *-jddif xzt1.xs5cv. o.6plror in the ammeter readings. A large systematic error results in measurements which are not accurate, in other words far from the correct value. Premsjdzd6.t . lv6b6 .x-*wfclp5zoi1xcision refers to how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
