O2 Ref :
Toxic gas measurements can be referenced to defined oxygen levels.
Reference values can be set from 1-20%, to AUTO or more normally
to the default value - OFF. Setting to AUTO uses the figure in the
FUEL constants data.
Oxygen referencing is required by some regulations such as TA-LUFT.
If a reference value is selected then toxic gas measurements will be
displayed with the symbol (n) attached to the reading. i.e. CO(n)
What does Oxygen reference mean ?
If 3 % O
2
reference is selected and 5 % O
2
is measured in the flue then
toxic gas values will be recalculated as if 3 % were measured. The
equation for referencing is detailed in the Appendix.
Oxygen referencing prevents false readings being submitted, e.g.
allowing more air into the boiler will increase the oxygen level in the
flue and hence dilute any toxic gas reading. Oxygen referencing gives
readings as if they were undiluted.
SMOKE:
Allows the user to enter a smoke test number from 0-9. This value will
be printed on the standard printout. Default value is OFF.
RESET : Allows
the user set the Oxygen to 20.9% and zero the toxic sensors
without turning the analyser off.
