MODE DESCRIPTION PARAMETERS
7 Out-of-Range Units = Samples
Samples Range = 1-200
Default = 5
This mode is used in conjunction with Out-of Range Span (Mode 8) to set an
effective window for valid readings. Setting the Out-of-Range Samples to 10
would require that a target be detected 10 times in succession outside of the
window (Mode 8) before the sensor will recognize it as a new valid target and
enter it into the FIFO buffer.
MODE DESCRIPTION PARAMETERS
8 Out-of-Range Units = Mode 1
Span Range = 0-9999
Default = 2.00 ft.
The Out-of-Range Span will set a certain size window (+/-) the current
reading. If the echo received is within this window, it will be considered valid
and is averaged in the FIFO buffer.
MODE DESCRIPTION PARAMETERS
9 Loss of Echo Units = seconds
Delay Range = 0-9999
Default = 5
This mode sets the delay in seconds before the output will show a loss of
echo condition. When the DCU-11 does not receive an echo, it will hold the last
valid condition for the number of seconds entered in Mode 9. When this time
has expired, the display and trip points will change to their maximum distance
reading.
