Measure and Learn

Set threshold

The Measure and Learn function in RRM automatically creates an Amplitude Threshold Curve (ATC) which is used by the Rosemount 5300 transmitter to find the surface pulse. The ATC is adapted to the shape of the measurement signal as described in “Disturbance Echo Handling” on page 7-7.

To create an Amplitude Threshold Curve (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, which creates an ATC that filters out all disturbing echoes. The ATC can also be manually edited if further fine tuning is needed.

The Configuration Mode window also allows you to manually change the amplitude thresholds simply by dragging the corresponding anchoring points in the plot to the desired positions. This option can be used to change the Interface Threshold.

Note that by manually changing the amplitude thresholds in the Echo Curve plot, the Automatic mode is disabled for the corresponding threshold (see “Threshold Settings” on page C-8for more information).

See “Surface Pulse Not Found” on page 7-5for more information on threshold settings.

The Set Thresholds button allows you to set the ATC to a fixed value based on the configured Dielectric Constant of the product.

See also “Threshold Settings” on page C-8for more information on how to adjust amplitude thresholds.
