CAUTION:
Do not enter the distance to the water surface or you will suppress the signal of the
water surface.
Also, this process will be more helpful if the water surface is low therefore exposing more
obstacles between the sensor and the bottom of the water body.
Command: 0XFES=18.5! (where 18.5 is the distance to water surface minus 1.5)
Response: 00412
Command: 0D0!
Response: 0+18.5+0
The sensor response to the
0D0!
command includes the sensor address (0) + distance to
suppress (18.5) + error code (0).
To remove the False Echo Map from the radar, reissue the command with the distance set
to 0.00 (ft/m) (
0XFES=000.00!
).
15. For some situations, you may want to narrow the radar measurement range. Narrowing the
measurement range can eliminate the possibility of return echoes that are outside the valid
distance range at a given location, which can cause the radar to return false readings. Also
limiting the measuring range improves the accuracy by limiting the distance range that the
radar is focusing on. The result will be improved data stability and accuracy. For instance, if
the maximum distance the radar will ever measure is 50 feet, changing the Measuring
Range to 52 feet will eliminate false reading beyond this.
Command: 0XXWMR=52.00!
Response: 00022
Command: 0D0!
Response: 0+52.00+0
The sensor response to the
0D0!
command includes the sensor address (0) + new
measuring range+ error code (0).
