 Setup → Advanced setup → Safety sett. → Ramp echo lost
Output echo lost (→  199) = Ramp at echo lost
Define the 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 (→  200) (positive value)
C Ramp at echo lost (→  200) (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 sett. → Blocking dist.
Specify upper blocking distance UB.
0 to 200 m
• For coax probes: 0 mm (0 in)
• For rod and rope probes up to 8 m (26 ft): 200 mm (8 in)
• For rod and rope probes above 8 m (26 ft): 0.025 * Sondenlänge
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
