Adjust thresholds using Rosemount Radar Master
Normally, the amplitude thresholds are automatically set by the Rosemount 5300
Transmitter, and no manual settings are needed. However, due to the properties of the
product, it may in rare cases be necessary to adjust the amplitude thresholds for optimum
measurement performance. Rosemount Radar Master supports threshold settings in the
Advanced Configuration window.
Prerequisites
Note
Before changing the amplitude thresholds, check that the Upper Product Dielectric
Constant parameter is set as accurately as possible. The Upper Product Dielectric Constant
is used for setting the automatically calculated amplitude thresholds.
Procedure
1. Select Setup → Advanced.
2. Select the Thresholds tab.
