In order to determine without bias the lowest ratio of a group, only the monitors specifically mentioned in that group shall be taken into consideration (e.g. a NOx sensor when used to perform one of the monitors listed in Annex 9B, Appendix 3, item 3 "SCR" will be taken into consideration into the "exhaust gas sensor" group of monitors and not in the "SCR" group of monitors)
Et kõrvalmõjudeta määrata kindlaks rühma väikseim suhe, võetakse arvesse üksnes seireseadmeid, mida on selles rühmas konkreetselt nimetatud (nt kui NOx andurit kasutatakse ühes 9.B lisa 3. liite punktis 3 „SCR” nimetatud seireseadmes, võetakse seda arvesse seireseadmete rühmas „heitgaasiandurid”, mitte aga seireseadmete rühmas „SCR”).
