The zero offset error 6 0bmtyr j8ony:97 llifu ws9(j-/mlpwill produce a systematic error in the ammeter readings. A large systematic error results in measurements which are not accurate, in othjm: 0s( 6f wut nyi-olry89lpl9/j7bmer words far from the correct value. Precision refers to how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
