A constant systematic error is one in which the magnitude of the error remains the same throughout the range of the test measurement.The error is proportional if the magnitude varies relative to the result.This is not a random error,which happens only infrequently and is not predictable.Precision requires multiple measurements of the same specimen and evaluates the ability to consistently reproduce the result.
