9.3 External temperature compensation
External temperature compensation can be used with the petroleum measurement application or the
enhanced density application.
Note: The external temperature value is used only for calculation of the derived variable in enhanced
density applications or the CTL value in petroleum measurement applications. The temperature value
from the sensor is used for all other calculations that require a temperature value.
