OCF 6.1 Open Channel Flow Monitor
CALIBRATION cont.
Damping
Choose between OFF, FIR (Default), or LOW PASS.
When measured flows are outside the Window of the running
average, the FIR filter will reduce the damping average so
that a fast response can be made to the sudden change in flow
rate.
The LOW PASS filter will ignore measured flow rates
outside the Window, while holding the running average, until
there are enough data points outside the Window to cause a
step-response to the new measured value.
While measured flows are within the Window of the running
average, both the FIR and LOW PASS filter behave the same.
Percent
Set the damping value for level reading. Lower values provide
fast response to changing levels, and higher values provide a
slower response. Factory default value is 10%.
Window
The Window sets a boundary around the running average,
where if the measured value falls outside the window, the
meter will make a more rapid response to the new value (FIR),
or will hold the last reading until enough values are outside the
window and then make a step response to the new value
(LOW PASS).
