1.1 The analysers shall have a measuring range
appropriate for the accuracy required to measure the concentrations
of the exhaust gas components (see 1.5). All analysers
shall be capable of continuous measurement from the gas stream and
provide a continuous output response capable of being recorded. It
is recommended that the analysers be operated such that the measured
concentration falls between 15% and 100% of full scale.
1.2 If read-out systems (computers, data loggers, etc.)
that provide sufficient accuracy and resolution below 15% of full scale are used,
concentrations below 15% of full scale may also be acceptable. In this case, additional
calibrations shall be made to ensure the accuracy of the calibration curves (see5.5.2 of appendix 4 of this Code).
1.3 The electromagnetic compatibility (EMC) of
the equipment shall be on a level to minimise additional errors.
