left side:
TF = waste gas temperature
O = oxygen volume content in dry waste gas

QF = calculated waste gas loss
Lam = air surplus number
right side:
Ta or TA = combustion air temperature
CO = carbon dioxide volume content in dry waste gas

If the waste gas temperature (DF) and oxygen content (0
key will be double-clicked for "freezing" the values. The central section is being
crossed by the letter sequence "B R E A K". The values may be recorded. Further
double-clicking will continue the measuring procedure. Pressing once will switch into
the second display field (cfr. chapter 3.2.2).

ETF = efficiency
CON = condensate amount
CO = carbon monoxide content in undiluted waste gas
PD = pressure differential or chimney draught

interface)
When this display field is called up first, no values will appear under CO and PD as yet.
Press once for measuring these values and move thus into the next display field.
