Kane KANE900 Plus - 12. PRODUCT SPECIFICATION

KANE900 Plus Operators Manual Page 30
AMBIENT : Temperature measured by the internal sensor, used in the NET
(Ta) temperature calculation if an INLET probe is not fitted.
CO/CO2 R : The CO/CO
2
ratio, is the ratio of measured CO divided by
calculated CO
2
.
It gives an indication of the following :-
• How good a gas sample the instrument is reading.
• How clean the boiler is running.
For example : A new or clean domestic boiler will display a ratio of
less than 0.004, a unit in need of cleaning 0.004-0.008 and a unit in
need of major overhaul will show greater than 0.008.
This only shows a reading when a combustion test is being carried
out. ‘- -’ is displayed while in clean ambient air.
P INDEX : The CO/CO
2
ratio expressed as a percentage %, called the ‘Poison
(PI) Index’ i.e. P INDEX % = 100 x CO/CO
2
. ‘- -’ is displayed while in
clean ambient air.
XAIR % : Excess air calculated from the measured oxygen and type of fuel
(λ) used. During a combustion test ‘O2 > 20%’ will be displayed while
in clean ambient air.
Prs : Flue draught pressure reading. Displayed when pressure sensor
fitted. See UNITS menu 5.2.3. for scales.
NO: Nitric Oxide reading in ppm or mg/m3. Displayed when Nitric
Oxide sensor fitted. Also displayed as NO (n) when referenced to
oxygen. The display will read ‘O2 > 20%’ if referenced values
selected and instrument is in clean ambient air.
NOx : Calculated total Nitric oxides displayed in ppm or mg/m3. Where
NOx = NO + P%NO, note P can be set from 0-9%, default = 5%.
See SELECT menu 5.2.2. Also displayed as NOx (n) referenced to
oxygen. The display will read ‘O2 > 20%’ if referenced values are
selected and instrument is sampling clean ambient air.
SO2 : Sulphur Dioxide reading in ppm or mg/m3. Displayed when Sulphur
Dioxide sensor fitted. Also displayed as SO2 (n) referenced to
oxygen. The display will read ‘O2 > 20%’ if referenced values
selected and instrument is in clean ambient air.
O2 ref % : Toxic gas measurements can be referenced to defined oxygen levels.
(O2r) See SELECT menu 5.2.2 for details.
