Step Eight
UPDATE AN EXISTING FALSE ECHO CURVE
This function enables an Existing False Echo Curve to be updated under the circumstances that the curve was
created when the level was higher than an empty tank condition.
Note: This function should only be performed
to update an Existing False Echo Curve when the level is BELOW the original False Echo Curve. Do not use
this function to update an Existing False Echo Curve when the level is above the original False Echo Curve.
Before starting, measure and note the exact distance from the sensor’s measurement location to the media
surface. Setting the distance value too large or too short can force the sensor into ignoring the true level.
