Page 15: Sensor Health Table
6.2.6. Sensor Health Table The instrument records a data quality ID between 0 and 7 with each reading. This ID indicates whether errors occurred during the reading. It is stored in the instrument’s data quality register. See the table below for details. Abbreviation Data Quality Text... - Page 16 4 Sensor Warm-up Sensor is warming up, sentinel value supplied. 5 Sensor Warning Parameter measured but does not meet normal quality criteria. The sensor has sustained moderate damage, or the recommended lifespan has been reached. 6 Sensor Calibrating Sensor is calibrating, calibration value supplied.

7. Calibration Connect the ODO-TX to a computer using the RS485 connection and open Commkit communication. Alternately, connect the ODO-TX to an appropriate controller or PLC with calibration capability. If using a PLC or controller to calibrate, refer to your controller manual. You can either perform a one-point or two-point calibration as noted below. -
Page 18: Maintenance
8. Maintenance 8.1. Cleaning Probe maintenance includes cleaning the sensor cap, as well as the proper conditioning, preparation, and storage of the test system. With the membrane sensor cap and guard cap installed on ODO-TX, gently scrub the probe with a soft-bristled brush or nylon dish scrubber. Use Alconox or similar cleaning solution to remove grease or other matter. -

2. Place the sponge wafer in the bottom of the calibration chamber and saturate with approximately 10 mL water. 3. Gently dry the instrument and sensing material with a paper towel, making sure there is no water or debris on the instrument or on the sensing surface. 4. -
Page 21: Inline Mounting With The Am-Tee-5
To mount the ODO-TX on the AM-ARM-5: Guide the probe cable from the 1” NPT fitting side from the front end of the submersion arm all the way through and back out the back. Loosen the strain relief, thread the cable through, and tighten it. Slide the aluminum wire mounting bracket onto the probe. - Page 22 To mount the ODO-TX probe in the AM-TEE-5: 1. Insert split ring and nut aver the sensor. 2. Screw the ODO-TX into the 1” Insert bushing. 3. Slide the bushing assembly into the tee and screw on the compression nut. Install lock nut into a groove to keep the nut attached to the assembly.

Page 32: Appendix C: Definitions
Appendix C: Definitions Live Salinity Value The live salinity value is used to correct the oxygen concentration value for salinity. Values must be written in Practical Salinity Units (PSU) in the range 0 to 42 PSU. This is not a measured parameter. Default Salinity Value The default salinity value is loaded into the live salinity value register when power is first applied to the probe. - Page 33 These values represent the slope and offset that will be applied to the raw concentration reading from the sensor to generate the final values reported by the sensor parameters. These registers may be written independently of the normal internal calibration procedure. Entering Calibration Registers The sensor is calibrated using the following procedure.
