SETTING THE KEEL OFFSET
The Echo Sounder measures the depth from the transducer to
the seabed. If the craft has a keel it is more often convenient to
show the depth from the keel to the seabed. To operate in this
way the depth of the keel (keel offset) must be entered into the
instrument as follows:
Put the instrument into the configuration mode. The display will
now show SET ENG. Press SPEED, the upper half of the
display will show USET and the lower half the current keel
offset value. Use TRIP to decrement and TOTAL to increment
this value. Pressing SPEED will enter this new value. The
display will briefly show CON to confirm the operation and then
return to the SET ENG display. If no further settings are to be
made then pressing the ILLUM key will exit the configuration
mode and return to normal operation.
