Esempio:

 Se il certificato della bombo-

la indica il valore di 1,27%v/v 
(=25,4%LIE) Metano, il LIE del Metano 
è 5%v/v e si deve verificare un sensore 
Mod.TS292PX-S tarato per Butano va 
utilizzato il “

”=2,04 come indicato in 

Tab.3 per ottenere:

Exemple:

 If the test label on the sample 

gas bottle shows 1,27%v/v Methane 
(=25.4% LEL) and Methane’s LEL is 
5%v/v, to verify a detector model 
TS292PX-S calibrated for Butane, use 
the correspondig “

(=25,4%LIE) Méthane et sa LIE est 
5%v/v et on doit verifier un capteur
