Press again and the display header screen will be shown.
NOTE: When the “CHARGING BATTERY” screen is displayed fast charging
mode is operating.)
And then the initializing screen is shown:
The time will count down in seconds to zero and is pre-set by the analyzer.
During countdown the analyzer will initialize the measuring system, do not block
the end of the probe or insert into or near the vehicle exhaust. It also displays
some setup values including atmospheric pressure and internal ambient
temperature.
TIP: Take care to purge the analyzer in really fresh air. Often the air in a
garage or workshop is contaminated with HC up to about 1 meter from
the floor with the emissions from past spills of oil, lubricants etc that may
have soaked into the floor.
Once the initialization is completed the analyzer will zero the CO, HC, CO
2
and
NO sensors if fitted and set oxygen to 20.9%. Keep the analyzer and exhaust
probe sampling fresh air.
