in this Paragraph “Step 2".
With reference to Table 6.1 Gas type identication values 18. → 67 and the fumes
analyser reading, check that the dierence between the CO

percentage obser-
ved in step “15” and the current reading corresponds to the delta CO

characte-
ristic of the gas being used.
Example: having set, in step "15", a CO

content of 9.5% for G20 gas, at step "18" the
reading should be 9.0% (=9.5%-0.5%).
If the dierence satises the delta CO19.
