The PC-based group has finished soldering all the connecting cables, polished the boxes for ME sensors and circuit boards and connected them with each other. All connection points were tested to prevent short circuit. That means, that both fluxgate and ME sensors are ready to be tested together. The first step in this direction will be to test them on the surface and if this test is successful, the prototype can be put underwater to prove its performance there.e of these errors was identified to be functionality issues with the wires.
