Use this feature, when monitoring solids (P002 = 2), if the reported level fluctuates
slightly, though the monitored surface is still. Enter the amount (in ms) of long shot Echo
Profile smoothing required. When a value is keyed in, the nearest acceptable value is
entered.
P825 Echo Marker Trigger
The point on the primary echo on which the measured value is based.
Use this feature if the reported material level fluctuates slightly, due to a variable rise in
the leading edge of the true echo on the Echo Profile.
Enter the value (in percent of echo height) to ensure the Echo Lock Window intersects the
Echo Profile at the sharpest rising portion of the Echo Profile representing the true echo.
This value is preset to 90% when P002=1 (Liquid) or 50% when P002=2 (Solid).
Advanced TVT Adjustment (P830 to P835)
Advanced TVT control applies to long shots only.
P830 TVT Type
Selects the TVT Curve used.
Values
Range: 5 to 95%
Preset: 90% when P002=1 (Liquid) or 50% when P002=2 (Solid)
