    CO/CO measurement CO measurement The connected 0632 1247 probe is initialised in the switch-on phase. For this reason the measuring instrument should only be switched on in a CO-free environment, otherwise the values subsequently measured may be too low! For further initialisation in a switched on instrument, place the probe in a CO-free environment. Allocate one of the function buttons with CO=0 and then press this function.
