Perform preliminary processing / analysis of data to ensure you have uploaded all data, that data was not corrupted in upload process, and that (if uploading converted data) instrument EEPROM was programmed with correct calibration coefficients. If there is a problem with data, you can try to upload again now. Once you record over data in next deployment, opportunity to correct any upload problem is gone.

If memory is not initialized, data will be stored after last recorded sample.

See instrument manual for example calculations.

Even if you think there is adequate battery capacity left for another deployment, cost of fresh batteries is small price to pay to ensure successful deployment.

1. Click Capture in terminal program and enter file name to record instrument setup, so you have complete record of communication with instrument.
2. Set current date and time.
3. Establish setup / operating parameters.
4. If desired, set date and time for sampling to automatically begin.
5. Send Status command (DS or #iiDS) to verify and provide record of setup. **
6. Send Calibration Coefficients command (DC, #iiDC, DCal, or #iiDCal) to verify and provide record of calibration coefficients. **

Remove protective plugs that were placed in Anti-Foulant Device caps or remove Tygon tubing that was looped end-to-end around conductivity cell to prevent dust / dirt from entering cell.
Note: Deploying instrument with protective plugs or looped Tygon tubing in place will prevent instrument from measuring conductivity during deployment, and may destroy cell.

Rate of anti-foul use varies greatly, depending on location and time of year. If you think there is adequate capability remaining, and previous deployment(s) in this location and at this time of year back up that assumption, you may not choose to replace Anti-Foulant Devices for every deployment. However, as for batteries, cost of fresh Anti-Foulant Devices is small price to pay to ensure successful deployment.

See instrument manual for configuration.

1. Click Capture in terminal program and enter file name to record instrument setup, so you have a complete record of communication with instrument.
2. If you did not set up instrument with a delayed start command, send command to start sampling.
3. Send Status command (DS or #iiDS) to verify and provide record that instrument is sampling. **
4. Send Send Last command (SL or #iiSL) to look at most recent sample and verify that output looks reasonable (i.e., ambient temperature, zero conductivity, atmospheric pressure). **
5. If instrument has pressure sensor, record atmospheric pressure with barometer. You can use this information during data processing to check and correct for pressure sensor drift, by comparing to instrument’s pressure reading in air (from Step 4).

Note: For instrument with pump (external or integral), avoid running pump dry for extended period of time.

Failure to correctly install cables may result in connector leaking, causing data errors as well as damage to bulkhead connector.

Verify that hardware is secure.

Connect to instrument in terminal program and send command to stop sampling (Stop or #iiStop). Stop sampling as soon as possible upon recovery to avoid running pump dry for an extended period of time (for some instruments, pump turns off automatically when conductivity frequency is below programmed minimum value). **

You can use this information during data processing to check and correct for pressure sensor drift, by comparing to instrument’s pressure reading in air.

• If cell is not rinsed between uses, salt crystals may form on platinized electrode surfaces. When instrument is used next, sensor accuracy may be temporarily affected until these crystals dissolve.
• Note that vigorous flushing is not recommended if you will be sending instrument to Sea-Bird for post-deployment calibration to establish drift during deployment.
• For instruments with integral pump or integral pump and dissolved oxygen sensor (37-SMP, -SMP-IDO, -SIP, -SIP-IDO, -IMP, -IMP-IDO): Rinse all internal plumbing in addition to conductivity cell. If not rinsed between uses, salt crystals may form on pump impeller and/or on oxygen sensor membrane.

If pump head is not rinsed between uses, salt crystals may form on impeller. Over time, this may freeze impeller in place, preventing pump from working.

This will prevent dust / dirt from entering conductivity cell.
Note: For short term storage all instruments except IDO MicroCATs, see Application Note 2D: Instructions for Care and Cleaning of Conductivity Cells. For IDO MicroCATs, see Application Note 64: SBE 43 Dissolved Oxygen Sensor.

1. Connect to instrument in terminal program.
2. If you have not already done so, send command to stop sampling (Stop or #iiStop). **
3. Click Upload in terminal program to upload data in memory.
4. Perform preliminary processing / analysis of data to ensure you have uploaded all data, that data was not corrupted in upload process, and that (if uploading converted data) instrument EEPROM was programmed with correct calibration coefficients. If there is a problem with data, you can try to upload again now. Once you record over data in next deployment, opportunity to correct any upload problem is gone.

• Do not clean cell if you will be sending instrument to Sea-Bird for post-deployment calibration to establish drift during deployment.
• Clean cell if you will not be performing a post-deployment calibration to establish drift.

See instructions in instrument manual.

We typically recommend that instrument be recalibrated once a year, but possibly less often if used only occasionally. We recommend that you return instrument to Sea-Bird for recalibration. In between laboratory calibrations, take field salinity samples to document conductivity cell drift.

Notes:
1. We cannot place instrument in our calibration bath if heavily covered with biological material or painted with anti-foul paint. Remove as much material as possible before shipping to Sea-Bird; if we need to clean instrument before calibrating it, we will charge you for cleaning. To remove barnacles, plug ends of conductivity cell to prevent cleaning solution from getting into cell, then soak instrument in white vinegar for a few minutes. To remove anti-foul paint, use Heavy Duty Scotch-Brite pad or similar material.
2. If using lithium batteries, do not ship batteries installed in instrument. See Shipping Lithium Batteries for details.
