  • Page 16: Common Prerequisites For The Ms70 Sea Acceptance Test Procedures

    These are the common prerequisites for the MS70 Sea Acceptance Test procedures: • The MS70 system is installed as specified in the Installation Manual. • The sensor is connected to a communication port on the MS70 system. • The interface port is set up with the correct communication parameters.
  • Page 17 To detect unserviceable transducer elements and/or transceiver boards, you must compare the rectangles. During normal operation at sea the colours will be homogeneous. When operating the MS70 system in port, the colours will be less homogeneous due to the environmental noise and the shallow depth.

  • Page 18: Verifying The Communication With A Navigation System (Gps)

    (GPS) Accurate and reliable information from navigation systems are vital to the MS70 operation. The information provided by the navigation systems is used by the MS70 software. Navigational data are also included in the raw data export formats. The information from the navigation sensors are shown on the top bar.

  • Page 19: Verifying The Communication With A Synchronization System

    It can be set up to operate in either Master or Slave mode. Synchronization is required in order to avoid interference if the MS70 system is used simultaneously with other hydroacoustic instruments within the same frequency range. You do not need to do this test if the MS70 shall only operate in Standalone mode.
  • Page 20 Select Synchronisation Select synchronization mode. Select the synchronization delay. Make sure that the MS70 operates normally when triggered by the remote synchronization system. Make sure that the MS70 operates while additional hydroacoustic systems (sonars, echo sounders) are in synchronized operation.

  • Page 21: Verifying The Communication With The Motion Reference Unit (Mru)

    About this task The motion reference unit (MRU) measures the roll and pitch movements of the vessel. The information provided by the motion sensor is used by the MS70 system to stabilize the beams. This interface test was made during the Harbour Acceptance Test. However, that test was limited due to the static information provided by the sensor.
