sourcesuchasawalloutletwithadjustableowmeter,ora
cylinderwithadjustableow.
CorrectNOdosecanbecalculatedandadjustedeitherbythechangingofthemanualcontrol
valvepositionoradjustmenttheowrateoftheO

source(seesections6.12.1&6.12.2).
Monitoring of the dose should be carried out by connection of the sample line to the manual
bagging circuit.
