COMPARINGROX&RAPIDPULSESENSORS

The instructions and QA recommendations on these pages will be used to set up and calibrate YSI 6-

Series sondes for use in comparison measurements of optical and steady state dissolved oxygen sensors.

This document is not a substitute for the YSI manual or 6150 support documentation.

MINIMUM REQUIREMENTS

• All YSI 6-Series sondes used in this study must be updated to firmware version 3.08.

650 displays must be updated to version 1.19.

• EcoWatch PC software must be updated to version 3.18.

• All sondes must be tested, calibrated, and be in good working order to be part of this study.

• New software /firmware available at www.ysi.com

• Review Appendix M ROX OPTICAL DO SENSOR in your manual to become familiar with the

YSI ROX luminescent DO sensor before proceeding.

• Review the 6150 Description and Instructions for Use documents for probe installation

information.

DISCRETE SAMPLING

1. Install the 6150 ROX optical DO sensor into the spare optical port.

2. Connect the sonde to a PC. At the command prompt (#) type “MDO 1”. This command will

allow both the Rapid Pulse and the ROX DO sensors to sample simultaneously.

Note: MDO = Multiple Dissolved Oxygen. (1/ enable, 0/disable)

3. Enable the ROX sensor in the sonde’s Sensor Menu.

4. Enable the % and mg/l outputs in the sonde’s Report Menu.

5. Disable the sonde’s Auto Sleep RS-232 setting found in the Advanced Menu under “Setup”.

6. Recondition and prepare the Rapid Pulse DO sensor with a new membrane and confirm that all

diagnostics -- charge, gain, and Warm-up -- meet specifications.

7. Run the sonde in “Discrete Run Mode” at a four-second rate for 15 minutes to burn in the Rapid

Pulse sensor. Run in saturated air.

8. Calibrate the Rapid Pulse DO sensor in saturated air as you normally would. DO NOT

CALIBRATE THE OPTICAL DO PROBE AT THIS TIME!

9. Calibrate all other sensors and prepare pre-deployment and QA records.

10. The YSI factory-generated ROX DO calibration coefficients will automatically be transferred

into the sonde at initial sensor power up.
