I want to add an auxiliary sensor to my CTD (SBE 9plus, 16, 16plus, 16plus-IM, 16plus V2, 16plus-IM V2, 19, 19plus, 19plus V2, 21, 25, or 25plus). Assuming the auxiliary sensor is compatible with the instrument, what is the procedure?
Adding the sensor(s) is reasonably straightforward:
- Mount the sensor; a poor mounting scheme can result in poor data.
Note: If the new sensor will be part of a pumped system, the existing plumbing must be modified; consult Sea-Bird for details.
- Attach the new cable.
- (not applicable to 9plus used with 11plus Deck Unit) Using the appropriate terminal program — Enable the channel(s) in the CTD, using the appropriate instrument command.
- Using Seasave V7 or SBE Data Processing — Modify the CTD configuration (.con or .xmlcon) file to reflect the new sensor, and type in the calibration coefficients.
