Sea-Bird CTD - Board measurements and useful resources

Electronic-board tests, board extender, useful links, bibliography, and good practices.

Tests and measurements on electronic boards

To carry out tests and measurements on electronic boards while they are operating, the original guide recommends ordering a board extender from Sea-Bird. This board is inserted between the CTD chassis and the board being tested.

Board and circuit extender for intervention

Board extender used for measurements on electronic boards in operation.

This type of intervention requires method, caution, and traceability, because it involves handling powered boards in a complex instrumental chain.

It is important to keep both a digital and manual history (logbook) of board purchases, use, replacements, and troubleshooting.
