Example: Rapid Level Changes
If the DCR’s filtering is too slow and the level to be monitored is changing
rapidly, the display will seem to jump between readings instead of scrolling
smoothly as the level changes. To reduce the filtering and quicken the response,
mode 7 or 8 should be changed.
MODE VALUE DESCRIPTION
7 0.125 Sets the sampling interval to a shorter time requirement, thus
decreasing the interval between samples from the default of 250
ms to 125 ms.
8 10 Decrease the samples averaged so that the DCR can respond
faster.
Example: Ignoring Intermittent Obstacles
To prevent agitators, splashing, or other intermittent objects from being
detected even though they are occasionally in the ultrasonic detection beam:
MODE VALUE DESCRIPTION
9 40 Increase the Out-of-Range Samples before updating. If the
sample rate is set to 0.500 seconds, and mode 9 set to 40, then
the DCR will require at least 40 * 0.5 or 20 seconds of readings
outside of the filter window (Mode 10) before the display and
outputs will recognize a new target.
10 0.3 ft. Reduce the filter window for good readings. This will help
qualify only echoes at the surface level. If the level changes
rapidly, the average level indication may lag behind the actual
level. If this occurs, the actual level may move outside the filter
window if the window size is too small.
