Check the flatness of the frame
The mounting structures must not deviate from a flat surface
more than ± 0.2 mm. This can be checked by measuring
the relative vertical positions of the module mounting bars
on the frames. If the deviations are too large, this has to be
corrected before the modules are put in place

3 Install the modules
When the installation of the transducer arrays are done in
the frame, the transmit module has to be installed along the
keel and the receiver module has to be installed across the
keel. Therefore the angel between the transmit and receiver
transducer has to be 90° in a “T” or a “L” module.
During the installation, check that the procedure
Installing
the transducer modules on page 39 are followed.
