7.3.5 Using the Echo Curve Analyzer with a Field Communicator
The Field Communicator supports the EDDL with enhancements that allows viewing of the Echo
Curve, creating an ATC, and specifying amplitude thresholds, such as the Surface Threshold.
Viewing the Echo Curve
To view the Echo Curve:
1. Select HART command [2, 5, 2, 3].
F
OUNDATION fieldbus parameter:
TRANSDUCER_1300 > AMPLITUDE_THRESHOLD_CURVE
The Echo Curve appears on the display:
2. Use the Hand and Zoom tools to view specific parts of the Echo Curve. The drop down
list allows for choosing items, such as the different amplitude thresholds to be
displayed in the plot.
The Echo Curve plot also shows an ATC if available. See “ATC” on page 84 for more
information.
