7-37 In-Tank Setup Coefficient of Thermal ExpansionCoefficient of Thermal ExpansionIf 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 eachtank. The system requires these values to establish proper temperature compensation factors during a leak testand 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 typicalthermal coefficients for various fuels and liquids:Table 7-1.
