Step Ten
CHOOSE CURVE
This function sets which information is displayed.
Default is Echo Curve.
Echo Curve - Shows the echo return energy received
by the sensor over distance.
False Echo Curve - Shows the false echo returns
which are mapped out (not considered) by the sensor.
Output Trend - Shows recent history of where the past
level readings have occurred.
ECHO CURVE
This function shows the Echo Curve and allows the user
to zoom in and magnify information along the X-axis
and Y-axis.
X-zoom - Expands echo information along the X-axis.
Used to determine the location of an echo.
Y-zoom - Expands echo information along the y-axis.
Used to determine the energy of an echo.
Unzoom - Returns the display to the original setting.
SIMULATION
This function sets a fixed 4-20mA current output from
the sensor for purposes of testing devices receiving
information from the sensor. The simulated current
output may be set with the below three input methods:
Percent - This method uses percentage of span (0-
100%) to set the current output (4-20mA) between the
Empty and Full Configuration values with 100% equal
to 20 mA and 0% equal to 4mA.
Current Out - This method directly sets the current
output (4-20mA) to the desired value.
Distance - This method uses distance from the
sensor’s measurement location to set the current
output (4-20mA) between the Empty and Full
Configuration values.
