Parameters
2.2.2. Response Rate
Sets the reaction speed of the device to measurement changes in the target
range.
12
Use a setting just faster than the maximum filling or emptying rate (whichever is
greater). Slower settings provide higher accuracy: faster settings allow for more
level fluctuation.
2.2.3. Echo Lock
Selects the measurement verification process.
If a material agitator or mixer is used in the monitored vessel, Echo Lock should
be set for Maximum Verification or Material Agitator to avoid agitator blade
detection.

Note: Ensure the agitator is always running while SITRANS LR 460 is
monitoring the vessel, to avoid stationary blade detection.
