Press the EGA box (if enabled) in the Home screen in Figure 18.1.i to view the EGA Gas screen, which
shows the following information:
• EGA current status
• Current exhaust gases, temperature and efficiency values (in black)
• Commissioned exhaust gases, temperature and efficiency values if trim is enabled (in grey)
The graphs show the exhaust gas concentrations histories.
This data is logged for 24 hours on the MM. Use the buttons to change the timescale of the data
displayed and press and drag on the axis to zoom in/out of the graph.
This information is logged for 2 years on the DTI when connected with the MM.
Note: Power cycling the MM or changing fuel will reset the 24-hour history data log on the MM.
Press to force the EGA into an air calibration when it is next in a safe condition (not trimming and
