Maximum permissible error—legal measuring instruments
Schedule 12 Maximum permissible error—legal measuring instruments
(regulation 3, definition of maximum permissible error)
When comparing the error of an evidential breath analyser with the corresponding maximum permissible error, the maximum permissible error must be rounded to the value of the verification scale interval. The error of a reading indicated by an evidential breath analyser may be greater than the maximum permissible error by one least significant digit.
