KM9106 Operators Manual 58
NETT : Nett temperature calculated by deducting the internal AMBIENT
temperature
from the measured FLUE temperature. Displays in either
Centigrade C or Fahrenheit F and will display NOT FITTED if
flue probe not connected.
If an external INLET probe is used then INLET is deducted from
FLUE.
O2 :
Oxygen reading in percentage %.
CO :
Carbon Monoxide reading indicated in ppm or mg/m3. If the
figures are referenced to oxygen then the display will show
ppmn or mg/m3n. See Section 6.4 for oxygen reference. Note
with a high CO sensor fitted the reading will be displayed in
percentage %.
EFF (G) :
Combustion Efficiency calculation displayed in percentage.
Gross G or Net N can be set see Section 6.3. The calculation is
determined by fuel type see Appendix B for calculation. The
efficiency is displayed during a combustion test, 00.0 is
displayed while in fresh air.
CO2m:
Carbon Dioxide reading in percentage %
CO2 :
Carbon Dioxide calculation determined by the type of fuel. This
only shows a reading when a combustion test is being carried out.
Zero (0.0) is displayed while in fresh air.
FLUE :
Temperature measured by flue gas probe in Centigrade or
Fahrenheit. Will show ambient temperature after fresh air
calibration and NOT FITTED or FAULT if probe
disconnected.
INLET :
Temperature measured by the optional inlet air probe or stored
using the Flue probe See Section 6.5. The air probe is plugged
into the instrument through the INLET socket. This figure is used
to calculate the NET temperature instead of AMBIENT when
fitted.
AMBIENT :
Temperatrue measured by the internal sensor, used in the NET
temperature
