Transducer Disassembly/Reassembly

This section describes the disassembly and reassembly operations for the transducers.

Exchanging the Transducer Cable

See the "Transducer Cable Assembly" on page 135 section for items that come with the cable.
WARNING
Transducers are calibrated at the factory, and the calibration data for the measurement is stored on the
CPU board. Therefore NEVER replace the CPU board with one from another transducer.
Important when fitting the screw covers! Do NOT remove the screw covers from the frame to which
they are attached. Leave them in place, as it is the only way to align the screw covers correctly. They
detach from the frame when you press them into position.
To exchange a transducer cable:
Pierce a screw cover with a small, flat-bladed screwdriver. Important! Do NOT try to pry out a
1
screw cover from the side, without piercing it, as this will damage the transducer top cover.
Gently rock the screwdriver back and forth until the screw cover comes out. Repeat to remove all
2
three screw covers.
