Bar graph: Readings that can be selected are: CO, CO
2
, O
2
, HC, NOx, MPH, AFR,
and LAMBDA. On opening results the displayed readings will default to relevant
gases. For example, if the test was a CAT then CO, CO
2
, HC, NOx and O
2
will be
displayed. Because all gases are recorded during a test they can be added to the
graph by clicking on the gases in the DISPLAY bar down the left hand side of the
screen.
The scale of the Y axis can be changed to read any gas by selecting from the key
down the right hand side of the screen, double click on the gas required.
If preset cut off points are set in test then the gas colour will change to red over the
cut off point, therefore any area in red is in excess of the predefined acceptance level.
A horizontal guide line, moveable with the mouse, helps the user to read gas values.
For a print out of result, click on ‘Printer’ symbol in the top right hand corner of the
screen, when pressed you are prompted for language of print out – English, Spanish
or French. A prompt will be displayed for which graph is to be printed. The Garage
Details, vehicle details and time and date stamp will be added to the print out.
