1 General

  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.
