49. ysis may not be used as a confirmation of the correct mixture composition In these cases the analyzer can only be used as an aid for increasing the probability that such incorrect mixture composition will be determined before its use The correctness of the mixture composition must be established by the technology used to prepare it The correct preparation of breathing mixes for diving nitrox oxygen enriched air trimix a mixture of air oxygen and helium heliox a mixture of oxygen and helium reguires special knowledge and experience which is possible to gain for example through an appropriate course A failure to apply such knowledge can lead to an incorrect mixture even though the results of the analysis are seemingly correct Such a situation can also be the result of a failure to take into account the influence of temperature and compressibility an insufficient blending of the mixture and other factors Please remember that the analyzer can be broken or damaged and that the oxygen sensor is by its nature subject to ageing and thus its properties deteriorate Therefore always verify the measured data in another way such as by precise mixture preparation another analytical method etc In addition the measured value must be subject to critical assessment using a common sense approach and if it differs from the allowable variation of mixing accuracy it must be considered invalid Copyright Divesoft 2007 3 English 1 IDt
