P3402/C
Maximum Depth Options:
0 to 5,000 m in steps of 1 m
Maximum depth for the bottom detection algorithm. The
default value depends on the transducer installed. A
depth setting of 0 m disables the bottom detection
algorithm. See Minimum Depth description above.
Min. Depth Alarm Options:
0.0 to 4,999.9 m in steps of 0.1 m
Alarm when detected depth is shallower than depth
setting. A depth setting of 0.0 meter disables the alarm.
Max. Depth Alarm Options:
0 to 5,000 m in steps of 1 m.
Alarm when detected depth exceeds depth setting. A
depth setting of 0 meter disables the alarm.
Bottom Lost Alarm Options:
OFF
ON
Alarm when bottom detection is lost.
Minimum Level Options:
-80 dB to 0 dB in steps of 1 dB.
After bottom detection, the detected depth is decre-
mented in sample steps until the received echo signal
(volume backscattering strength) is below the
MINIMUM LEVEL setting. Refer to paragraph
BOTTOM DETECTION in section "Theory of Operation".
