Set threshold (P026)
This sets the sensitivity of the echo detection circuits in the transmitter. The threshold is a
percentage defining the minimum signal level, above which an echo is detected and treated as a
potentially valid surface or target.
When the threshold is set to “
Auto
”, the sensitivity is automatically adjusted over a range of
values, depending on the echo strengths being received. The threshold is adjusted to one
quarter of the peak value of the largest signal detected to give best overall performance. The
live value is indicated in the read-only
Threshold In Use
parameter (
).
The threshold can be a constant value, which may be needed to overcome on-site difficulties or
special conditions.
