Coefficient of Thermal Expansion
If necessary, press STEP until you see the message:
To ensure proper leak test performance, you must enter the Coefficient of Thermal Expansion for the fuel in each
tank. The system requires these values to establish proper temperature compensation factors during a leak test
and for use in calculating temperature compensated volume and density.
If you know your product’s thermal coefficient enter that value. Otherwise refer to Table 7-1 for list of typical
thermal coefficients for various fuels and liquids:
