If a material agitator (mixer) is used in the vessel monitored, set Echo Lock for maximum verification or material agitator to avoid agitator blade detection. Ensure the agitator is always ON while the MultiRanger is monitoring the vessel to avoid stationary blade detection.

When set for max verification or material agitator, a new measurement outside of the Echo Lock Window (P713) must meet the sampling criterion (P712).

For total lock, Echo Lock Window (P713) is preset to zero 0. The MultiRanger continuously searches for the best echo according to the algorithm chosen (P820). If the selected echo is within the window, the window is then centered about the echo. If not, the window widens with each successive shot until the selected echo is within the window. The window then returns to its normal width.

When Echo Lock is OFF , the MultiRanger responds immediately to a new measurement as restricted by the Max Fill / Empty Rate (P700 / P701); however, measurement reliability is affected.
