For combination curves, enter at least 2 breakpoints immediately before and after any
sharp angle (as well as 1 breakpoint exactly at the angle) on the curve. For more

Maximum Process Speed
The HydroRanger 200’s ability to respond to material level changes is designed to exceed
even the most demanding installation requirements.
The Maximum Process Speed setting automatically presets various parameters affecting
the HydroRanger 200 response to material level changes as follows:
If any of these parameters are independently altered, a Maximum Process Speed (P003)
parameter alteration automatically resets the independently altered value.
Slower Maximum Process Speed (P003) provides greater measurement reliability. Faster,
independently set Max Fill (P700) and Max Empty (P701). Rates may be impeded by Echo
Lock (P711), Scan Delay (P727), and Shot Delay (P728) values.
