Figure 33 – Swap Array and Swap Roll Check Boxes
Sea Trial - Commissioning Step 9: Array Polarity
With the WMB-160/80F running and displaying the sonar view, determine if the right
side of the sonar display shows topography that is on the starboard side of the vessel.
If you are unsure of the nature of the sea floor you will need to find a feature such as
a rock, bank or significantly sloped sea profile. Use the contour view to navigate and
cross your own track in opposite directions over this feature. If the display seems
incorrect, change the polarity of the
Swap Array
check box in the
Ship Setup
Options
,
Sensor Values
tab and record the new value below. See Figure 33.

Sea Trial - Commissioning Step 10 : Roll Correction Polarity
Watch the
sonar
view carefully when the vessel is subject to some roll. If the roll
polarity is correct the sea floor shown on the
sonar
view should stay steady as the
vessel rolls. If the roll polarity is not correct, the roll of the
sonar
display will double
what is actually present. If you are unsure, compare the results with the
Swap
Roll
check box selected and then de-selected. For an SC30 Swap Roll should be
enabled unless the Array or Antenna are swapped.
Note the correct polarity value below and leave the
Swap Roll
check box in that
state.
