• Rapid level changes
• Surface level within Blind Zone
• Disturbing echo
Check the tank to find out what causes
problem to track the surface.
• Set the Rapid Level Changes
parameter, see Rapid level changes.
• In the Blind Zones, the level may jump
to Full Tank/End of Probe
• See Disturbance echo handling.
Nearzone echo present An echo has been detected in the
nearzone.
No action needed.
Nonlinear gain used The nonlinear gain is enabled. No action needed.
Nearzone measurement The current sweep can be used as a
measurement of the nearzone.
No action needed.

Interface status messages that may appear on the Integral Display, on the handheld
communicator, in DeltaV, or in Rosemount Radar Master are shown in Table 7-5:
Table 7-5: Interface Status
Message Description Action
Interface not OK The interface measurement is not OK. Check other interface status messages
for reason.
Interface not found No interface available No action needed.
Interface threshold to high Adjust Interface threshold, see Example
