Page 30APPENDIX 1 - MAIN PARAMETERS:Here are the legends used and what they mean:O2 : Oxygen reading in percentage (%)O2R: Oxygen reference setting. '----' means switched off or set to0%.T Flue: Temperature measured by the flue gas probe in Centigrade. Itdisplays ‘- OC -’ if the flue probe is disconnected.T Inlet: The temperature measure from the flue probe during the freshair purge will be used as the inlet temperature. If no probe isconnected then the internal ambient temperature of theKANE255 will be used as the inlet.T Nett : Nett temperature calculated by deducting the AMBIENT orINLET temperature from the measured FLUE temperature.Displays in either Fahrenheit (F) or Centigrade (C) or andwill display ‘- - -’ if the flue probe is not connected.COp: Carbon Monoxide reading displayed in ppm (parts permillion). ‘- - -’ is displayed if there is a fault with the COsensor or the instrument has not set to zero correctly, switchoff instrument and try again.COm: Carbon Monoxide displayed in mg/m3 .COn: Carbon Monoxide in ppm normalised to the O2R value viewedon the AUX screenCOM: Carbon Monoxide in mg/m3 normalised to the O2R valueviewed on the AUX screenR: CO/CO2 Ratio: measured CO divided by measured CO 2CO2 : Carbon Dioxide calculation determined by fuel type. This isonly displayed when a combustion test is being carried out. ‘-- -’ is displayed while in fresh air.
