The zero offset error will produce a systematz6z xtlorc0r-mi ogj -dgm 4j)/p5; :lic error in the ammeter readings. A large systematic error results in measurements which are not accurate, in other words far from the cor;o-rjgm4r50m l iz c:-z6 xpdgj/lt)o rect value. Precision refers to how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
