A - Main Display Parameters
The parameters and their meanings are detailed as follows:
FUEL:
The selected fuel will be displayed, i.e. GASOLINE. See
Select menu
section 5.2.2 to change.
• GASOLINE – Leaded or Unleaded gasoline/gasoline.
• LPG – Liquid Petroleum Gas
• CNG – Compressed Natural Gas
DATE:
Analyzer date. See
Set-Up menu
section 5.2.5 to change.
TIME:
Analyzer time. Use
Set-Up menu
section 5.2.5 to change.
BATTERY:
Displays the battery level from 0-100%. The analyzer will flash
(BAT)
RECHARGE BATTERY
at less than 10 % of charge. With the charger connected the display
shows
AC ON
.
NOTE!
Allowing the battery to discharge fully may destroy it.
O2:
Oxygen measured in the exhaust gas indicated in percentage %. With the pump off the
analyzer will display - - - -. If there is a fault with the oxygen sensor then FLT will be displayed.
CO:
Carbon monoxide measured in the exhaust gas indicated in percentage %. With the pump off
the analyzer will display - - - -. If there is a fault with the CO reading then
FLT
will be displayed.
CO2:
Carbon dioxide measured in the exhaust gas in percentage %. With the pump off the analyzer
will display - - - -. If there is a fault with the CO2 reading then
FLT
will be displayed.
HC:
Hydrocarbons measured in the exhaust gas indicated in ppm (parts per million) n-hexane
(gasoline). With the pump off the analyzer will display - - - -. If there is a fault with the HC
reading then
FLT
will be displayed.
COK:
Generally known as corrected CO. This value is calculated and used for comparison with the
actual infra-red measured CO value. COK = (Cox15)/(CO + CO2), for normal car exhaust CO +
CO2 = about 15%. In this case CO is approximately equal to COK. If COK is clearly higher
than CO this indicates defects such as exhaust leaks. At near zero COK is not valid.
OIL:
Oil temperature as measured by the dip stick probe. Displays in either ˚C (deg C) or ˚F (deg F)
and will display N/F if the probe is not connected.
