Static error of a measurement is defined as

  • A.the smallest change the instrument can detect
  • B.the indicated value less the true value
  • C.the true value less the indicated value
  • D.the ratio of the indicated value to the true value

Answer: B

Correct answer: the indicated value less the true value

\[ e = A_m - A_t. \] The sign convention matters: an instrument reading high has a positive error, and the correction to be applied is therefore negative. Reversing the order gives the correction rather than the error, which is why calibration certificates state explicitly which they are quoting.
