Section 4 Overview 4.1 Operation overview The SBE 9plus continuously measures conductivity, temperature, pressure, and parameters from up to eight auxiliary sensors in salt or fresh water at depths to 10,500 m. It is designed to take vertical profiles at 24 scans/second. The main housing contains the data collection electronics, telemetry circuitry, and a ®... - Page 16 Overview 9plus and a programmable table of bottle-close pressures to control the Carousel so the bottles close upon upcast.

Set up sensor and verify operation 5.2 Install software and test sensor Make sure that the sensor is connected to a power supply and PC through the serial connector on the supplied cable. Most PCs no longer have serial ports, and a serial-to- USB adapter is necessary. -
Page 20: Pump Operation
Set up sensor and verify operation 5.4 Pump operation The control logic for pump operation is based on the output from the primary conductivity connection (JB2). If the 9plus has redundant sensors and is to be deployed with the primary conductivity sensor removed, connect the secondary temperature and conductivity sensors to JB1 and JB2. -
Page 21: Section 6 Deployment And Recovery
Section 6 Deployment and recovery 6.1 Component positions for deployment The 9plus is typically deployed in a vertical position. When used with a 17plus/32 Carousel Water Sampler, the 9plus is deployed horizontally. The system is delivered by the manufacturer as specified by the user at the time of purchase. Note that if the pump and plumbing are not placed in the correct position, they can trap air and will not operate correctly. -
Page 22: Recommendations For Quality Data
Deployment and recovery • Put the (optional) DO sensor intake above the conductivity sensor exhaust. • Put the pump intake above the DO sensor exhaust. • Put the pump exhaust outlet corner up. • Put a 13 mm long piece of 9.5 mm ID Tygon tubing at the (optional) SBE 43 dissolved oxygen (DO) intake and exhaust. -

Deployment and recovery to sample on an upcast as well, attach the redundant T and C sensors on the upper and lower ends of the cage: one pair moves through undisturbed water on the downcast, and the other pair moves through undisturbed water on the upcast. In a horizontal configuration with a Carousel Water Sampler, for example, the upcast data is better because the sensors are attached to the outside edge of the system. - Page 24 Deployment and recovery a. Frequency channels suppressed: • 0 = 3plus or 4C connected to JB5 (COND 2). • 1 = 3plus or 4C connected to JB4 (TEMP 2) and not JB5. • 2 = no redundant temperature or conductivity sensors. b.

Page 25: Recover System
Deployment and recovery • Use Seaterm software for the 11plus Deck Unit and the 9plus. • Use Seaterm AF software for the 17plus Searam and the 9plus. 6. Install a cable or dummy plug on each bulkhead connector on the 9plus. 7. - Page 26 Deployment and recovery 22–24 Voltage output from A/D channels 2–3 (12 bits each) 25–27 Voltage output from A/D channels 4–5 (12 bits each) 28–30 Voltage output from A/D channels 6–7 (12 bits each) 31–36 Expansion (all zeros) — The Searam and Deck Unit do not show channels that are not used, based on the setup of the configuration file.

Page 35: Section 8 Calibration
Section 8 Calibration The manufacturer calibrates every sensor to known conditions and measures the response of the sensor. Calibration coefficients are calculated and are used to get engineering units. 8.1 Conductivity The SBE 4C conductivity sensor has a fixed precision resistor in parallel with the cell. When the cell is dry and in air, the output frequency of the resistor is the same as the electrical circuitry of the cell. - Page 36 Calibration The software converts psia to decibars: Decibars = (psia - 14.7) × 0. Convert the 9plus from gauge to absolute: add 14.7 psia: -2.5 dbars + (14.7 psi × 0.689476dbar/psia) = -2.5 + 10.13 - 7.635 dbars. Offset = 10.1050 - 7.635 = 2.47 dbars. Enter this value in the .xmlcon or .con file. Use a dead-weight pressure generator to calculate slope and offset values 1.
