Filtering (Modes 7-9)
The filtering modes are provided to adjust how fast the system will respond
to target changes. The default settings should be appropriate for most level
applications. However, the filtering can be changed to increase or decrease
reaction time to keep up with fast moving targets and filter out unwanted
targets.
MODE DESCRIPTION PARAMETERS EXPLANATION
7 Sample Rate Units = seconds
Delay Range = 0.075 – 1.0 sec.
Default = .250 seconds
8 Samples Range = 1 - 50
Averaged Default = 20 samples
9 Out-of-Range Range = 1-50
Samples Default = 10 samples
10 Window Units = mode 1
Range = 0 - 20 ft.
Default = 2.00 ft.
Sets the delay between each
sample (or reading) taken by
sensor
Sets the number of samples to be
saved in the buffer memory and
averaged together. The average
is then displayed as the output
(distance, volume, or flow).
Samples are sent to the buffer on
a First-In-First-Out (FIFO)
basis. When the number of
samples in the buffer is equal to
the number entered in mode 8,
the samples are averaged and the
result is displayed as the output.
Sets the number of consecutive
sample readings outside the
*window that will be ignored
before the new target is
accepted. If a target is detected
outside the window and is
sampled in succession
the
number of times entered in mode
9, then it will be accepted as a
target by the sensor. *(see mode
10)
Sets the window of target
acceptance. The window is equal
to + or – the value entered in
mode 10 from the current
