The Configuration Mode tab
The Configuration Mode tab allows for adjustment of the different amplitude thresholds. When selecting
the Echo Curve icon under Device Config/Setup, the Echo Curve Analyzer window appears with the
Configuration Mode tab selected:
Figure 7-8. Echo Curve Analyzer Plot in Configuration Mode
The Measure and Learn function in RRM automatically creates an ATC used by the Rosemount 5400
Series transmitter to find the surface pulse. The ATC is adapted to the shape of the measurement signal
as described in “Echo tuning” on page 109.
To create an ATC, click the Learn button in the Echo Curve Analyzer/Configuration Mode window. By
clicking the Learn button, the Measure and Learn function is activated and creates an ATC that filters out
all disturbing echoes. The ATC can also be edited manually if further fine tuning is needed.
The Configuration Mode window also allows the changing of the amplitude thresholds manually, simply
by dragging the corresponding anchoring points in the plot to the desired positions.
Note
By changing the amplitude thresholds in the Echo Curve plot manually, the Automatic mode is disabled
for the corresponding threshold.
The Set Thresholds button sets the ATC to a fixed value based on the configured Dielectric Constant of
the product.
To register a false echo, right click and select Register as false echo.
