Kongsberg Simrad SU90 Manual page 37

• The SU90 system is turned on and operates normally.
• The SU90 system is in Normal mode, but
transmissions.
• The transducer is retracted to its upper position.
• The vessel is berthed.
Caution
You must never set the SU90 system to "ping" unless the transducer is submerged in
water. The transducer may be damaged if it transmits in open air.
Neither tools nor instruments are required.
Context
By means of the
Element BITE
easily determine if the SU90 hardware is operational. The following pages are provided:
Matrix
The page allows you to monitor the average signal values or signal phases
Matrix
from each of the channels and transducer elements in the SU90 system. The
presentation is provided on a matrix corresponding to the element locations in
the transducer.
B-Scan
The page allows you to monitor the data received from each of the elements
B-Scan
in the transducer. The start sample and the number of samples to be displayed
are selectable.
In the B-Scan presentation, each element in the transducer is shown as a long
coloured vertical rectangle. If you place the cursor on top of one of these
rectangles, a small yellow tool-tip will identify key information about the channel.
• The identification of the transducer element
• The identification of the transceiver board
• The current sample you are looking at
• The measured echo value (in dB)
Note
This test can only be done if the water depth allows the transducer to be lowered
completely. If this is not the case, the vessel must be moved to another location, or the
test must be cancelled. Kongsberg Maritime cannot take responsibility for tests that are
cancelled for this reason.
If you are unable to do this test during the Harbour Acceptance Test, it must be repeated
during the Sea Acceptance Test.
