Reset DC Estimation: Resets DC estimation to the configured initial value,

forcing the device to start over estimating the product DC.

Use Static Product DC: Check this setting if you do not want the device to

estimate the product DC. This will force the device to use the configured initial

product DC.

ECHO TRACKING Measurement with the Rosemount 5300 is based on the fact that the radar

signal pulses are reflected by the product surface. Different parameters are

used to track the measurement signal to achieve a reliable and stable

measurement. Normally, the echo tracking parameters are automatically set

by the 5300 transmitter, and no manual settings are needed. However, due to

the properties of the product, in rare cases it may be necessary to adjust the

echo tracking settings for optimum measurement performance. RRM

supports echo tracking settings in the Advanced Configuration window,

Echo Tracking tab.
