Output echo lost (→  142) = Ramp at echo lost
Slope of the ramp in the case of a lost echo
Signed floating-point number
0.0 %/min
A Delay time echo lost
B Ramp at echo lost (→  143) (positive value)
C Ramp at echo lost (→  143) (negative value)
• The unit for the slope of the ramp is "percentage of the measuring range per minute" (%/
min).
• For a negative slope of the ramp: The measured value is continuously decreased until it
reaches 0%.
• For a positive slope of the ramp: The measured value is continuosly increased until it
reaches 100%.
 Setup → Advanced setup → Safety settings → Blocking distance
Specify upper blocking distance UB.
0 to 200 m
For rod and rope probes up to 8 m (26 ft): 200 mm (8 in)
Signals in the upper blocking distance are only evaluated if they have been outside the
blocking distance when the device was switched on and move into the blocking distance
