F.3.33 Threshold 1 size (P048)
False echoes may occur close to the transmitter face. If they occur outside the Upper Blanking
distance (page 131), the false echo can be ignored by entering the echo size as a percentage and
a time (representing distance). The echo size is set by the parameter Threshold 1 Size (P048).
See “Threshold 1 time (P043)” on page 137 for entering the time (representing distance).
Note
Use the read-only parameter Echo Size (page 154) as a reference for the false echo size.
See also “False echoes under certain ambient operating conditions” on page 62 for
additional information about adjusting the settings of parameters P043 and P048.
