to 10, where 0 indicates a low margin, and 10 indicates a high margin. It indicates how
much margin there is until the noise peak is indicated as the surface level.
Note
The signal amplitude and the noise margin depend on probe type and application
conditions, as well as the condition of the probe. Even if the probe is clean, the Signal
Quality may not be a 10.
Surface/noise margin
Surface/Noise Margin is the relationship between surface peak amplitude and the
amplitude of the strongest noise peak above the surface. The Surface/Noise Margin spans
from 0 to 10, where 0 indicates a low margin, and 10 indicates a high margin. It indicates
how much disturbance the device can handle in the tank.
Note
The signal amplitude and the noise margin depend on probe type and application
conditions, as well as the condition of the probe. Even if the probe is clean, the Surface/
Noise Margin may not be a 10.

Check if Signal Quality Metrics is supported
Procedure
To check if Signal Quality Metrics is supported, do one of the following:
• Check that DA1 or D01 is mentioned in the model code on the transmitter head.
• Check that “Diagnostics Suite” is mentioned in the Device Software Configuration 2 list.
a. Start Rosemount Radar Master and connect to device.
b. Right-click on the device and select Properties.
