A - Main Display Parameters
The parameters and their meanings are detailed as follows : -
DATE :
Analyser date. See Set-Up menu section 5.2.5 to change.
TIME :
Analyser time. Use Set-Up menu section 5.2.5 to change.
BATTERY :
Displays the battery level from 0-100%. The analyser will flash
(BAT) RECHARGE BATTERY at less than 10 % of charge. With the
charger connected the display shows AC ON.
NETT :
Nett temperature calculated by deducting the internal AMBIENT
temperature
( ∆T) from the measured FLUE temperature. Displays in either °C (C) or
°F (F) and will display NOT FITTED (N/F) if flue probe is 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 CO(n). See
SELECT menu 5.2.2 for oxygen reference. The display will read
‘O2 > 20%’ if referenced values selected and instrument is in clean
ambient air.
EFF (G) :
Combustion Efficiency calculation displayed in percentage. Gross G
or Net N can be set see SELECT menu 5.2.3. The calculation is
determined by fuel type see Appendix B for calculation. The
efficiency is displayed during a combustion test, ‘- -’ is displayed
while in fresh air.
CO2 :
Carbon Dioxide calculation determined by the type of fuel. This
only shows a reading when a combustion test is being carried out. ‘-
-’ is displayed while in fresh air.
FLUE :
Temperature measured by flue gas probe in Centigrade or
(Tf) Fahrenheit. Will show ambient temperature after fresh air
calibration and NOT FITTED (N/F) or FAULT (FLT) if probe disconnected.
INLET :
Temperature measured by the optional inlet air probe. This probe is
(Ti) plugged into the instrument through the RS232 socket. This figure is
used to calculate the NET temperature instead of AMBIENT when
fitted.
