UEi Test Instruments C75OILKIT - Manual (Page 12)

EFF (G): Combustion efficiency calculation displayed in percentage.
Gross (G) or Net (N) can be set (see MENU). The calculation
is determined by the fuel type and uses the calculation in
British Standard BS845. The efficiency is displayed during a
combustion test, “- - - -” is displayed while in fresh air.
XA IR % : Excess air calculated from the measured oxygen and type of
fuel used. Displays reading during a combustion test. “- - - -” is
displayed while in fresh air.
A MB : Boiler air INL ET t e m p e rature used to calculate the
NET t e m p e ra t u r e .
: Displays the approximate battery level as follow s :
• Full battery level
• B a t t e ry at 75 %
• B a t t e ry at 50 %
• B a t t e ry at 25 %
When the display flashes this, it indicates the batteries are at less than 10 %
of charge and should be replaced, readings may be affected if the analyzer
is used with low power batteries.

Main Display Parameters
O 2 : Oxygen reading in percentage (%).
T f : Te m p e rature is measured by the flue gas probe in Centigrade
or Fahrenheit. Will show ambient temperature after fresh air
ca l i b ration and “- - - -” if the flue probe is disconnected.
C O : Carbon Monoxide reading displayed in ppm (parts per
million). “- - - -” is displayed if there is a fault with the CO
sensor or the instrument has not set to zero correctly,
switch off instrument and try again.
C O a : Carbon Monoxide air-free reading referenced to an oxygen
level of 0%. Do not confuse this reading with the actual CO
reading as detailed above.
C O
2
: Carbon Dioxide calculation determined by the type of fuel.
This only shows a reading when a combination test is being
carried out. “- - - -” is displayed while in fresh air.
∆T : Net temperature calculated by deducting the A MBIENT
(or INL ET) temperature from the measured FL UE
t e m p e rature. Displays in either Centigrade (˚C) or Fahrenheit
(˚F) and will display “- - - -” if the flue probe is not connected.
