4. Factors tab
Option Description
Factors Small adjustments can be made to the measurements listed by entering a factor. This defaults to
1.000 for all measurements to indicate no adjustment. If this is changed then the measurement
calculated by the instrument will be multiplied by this factor to give an adjusted measurement value.
5. Options tab
Option Description
Headspace Check this box for a fast measurement sequence that provides data from the
headspace only.
Equilibrated This is only available if Headspace (previous box) is checked. Check this box if you
require the additional total O
2
and dissolved CO
2
measurements taken from the
headspace.
Slow decompress If checked, then after the measurement process has completed, a slow release of any
remaining pressure will take place so the package can be handled safely.
Flow multiplier This defaults to 1. Set this value to between 0.5 and 5 to decrease or increase the time
taken for the pressure release process at the end of the measurement. The higher the
value, the quicker the pressure is released. This is especially useful for large packages.
HS measurement
pressure drop
This defaults to 0.5 bar. Set this value to between 0.1 and 5 bar. When the pressure
has decreased by this amount, the headspace measurement stops. This is useful for
packages that contain a gas widget. This parameter can be used to determine if the
headspace is measured before or after the gas from the widget is released. If foam is
detected during the headspace measurement or during the sonication, it is advised to
reduce this value. It will also reduce the analysis time. However, if this value is too small
the accuracy of the HS O
2
measurement will be reduced.
