    Low noise is a key factor for high quality and reliable measurements. The performance of the SN90 will always be limited by different noise sources. A high noise level will mask the echoes and make them difficult to read and interpret. The noise is measured while the SN90 operates in Passive mode with the transducer disconnected.

  • Page 41 Neither tools nor instruments are required. Caution You must never set the SN90 to "ping" unless the transducer is submerged in water. The transducer may be damaged if it transmits in open air. For the best possible conditions to complete the test, the ship must be "silent".
  • Page 42 Make sure that the water depth under the keel permits you to lower the transducer. Lower the transducer to its bottom position. Do the following preparations. At the bottom of the SN90 presentation, select a suitable presentation mode, and activate the Horizontal view. Open the menu.
  • Page 43 If faulty channels are grouped together on the transducer face, this may cause a visible defect in the SN90 presentation. If they are scattered, the visible defect may be a lot harder to see. In all cases, the echoes from the neighbouring channels cause an interpolation that will restore a lot of the degraded presentation.

When you move the cursor over the B-Scan presentation of the SN90 transceiver channels, each element in the transducer is clearly identified as a long coloured vertical rectangle.
  • Page 46 Look at the pattern in the B-Scan presentation, and compare them with the example provided. The sample frequency in the SN90 is 5 kHz. Since the sound travels approximately 750 meter back and forth every second, each sample will cover 750 m divided by 5000 Hz, which is approximately 15 cm.

  • Page 65: Verifying The Installation Parameters For The Motion Reference Unit (Mru)

    (MRU) The physical location of the motion reference unit (MRU) relative to the transducer is required to allow the SN90 to adjust for roll and pitch as accurately as possible. Prerequisites For accurate location of the motion reference unit (MRU), you need the detailed vessel drawings.
  • Page 66 For maximum accuracy, we strongly recommend that you use the information provided by a dimensional survey. Neither tools nor instruments are required. The SN90 is turned on, and it is working normally.
  • Page 67 - and other GPS systems - allow you to define the MRU location in the positioning system. If this is done, the MRU offset values in the SN90 must be set to 0 (zero) to avoid "dual compensation". The rotation information is normally not recorded by the positioning system, and must therefore be defined in the SN90.
