This manual explains setup, software, sensor options, and maintenance for the C3 underwater fluorometer by Turner Designs.
The C3 underwater fluorometer can be equipped with up to three optical sensors covering a spectral range from ultraviolet to infrared, a temperature sensor, and a depth probe rated to 600 m. The instrument includes optional pressure sensors and mechanical brushes, and it is controlled via a Windows‑based C‑Soft interface for calibration, data logging, and data transfer.
The manual provides detailed instructions for unpacking, mechanical installation, cable connections, and software installation. It also covers the C‑Soft user interface, data capture, calibration procedures, and maintenance tasks such as cleaning and connector care. Appendices describe cable pinouts and the use of secondary solid calibration standards. This manual is written in Chinese.
