(1)Available only if Gas Standard Volume is not enabled.

(2)Available only if Gas Standard Volume is enabled.

(3)Requires the petroleum measurement application.

(4)Requires the enhanced density application.

(5)Default variables are mass flow, temperature, density, volume flow, and drive gain, respectively. See Section 8.10.3 for information on specifying the variables.

7.4Using the LEDs

The user interface module provides three LEDs: a status LED, a module LED, and a network LED (see Figures 3-1and 3-2).

•For transmitters with a display, the LEDs can be viewed with the transmitter housing cover in place.

•For transmitters without a display, the transmitter housing cover must be removed to view the LEDs (see Section 3.3).

For more information:

•On using the module LED, see Section 7.4.1.

•On using the network LED, see Section 7.4.2.

•On using the status LED, see Section 7.5.1.

7.4.1Using the module LED

The module LED indicates whether or not the transmitter has power and is operating properly. Table 7-3lists the different states of the module LED, defines each state, and provides recommendations for correcting problem states.
