Page 12: Maintenance
Maintenance Sensor: There are no user-serviceable parts. If problems develop with sensor stability or accuracey, contact Seametrics. If the unit has been exposed to hazardous materials, do not return without notification and authorization. Cable: Cable can be damaged by abrasion, sharp objects, twisting, crimping, crushing, or pulling. -
Page 13: Troubleshooting
Next, check the cable for cracking or fraying. If the connections and cable appear OK, but the readings are still erratic, the transmitter may be damaged. Contact Seametrics for evaluation and repair. Erratic and erroneous readings can also occur due to improper grounding. See Grounding Issues, below. -

Page 16: Appendix B: Field Calibration
If there are any sessions on the sensor, upload any data you want and then erase the session before continuing. Place the DO2 sensor in your reference solution, allow a few minutes for temperature to stabilize. Obtain the DO saturation using an alternate method, then select the calibration button. -
Page 17: Appendix C: Reading The Seametrics Do2 Sensor Via Direct Read
Power On Function In order to save power, the power to the sensing probe on the DO2 is normally off, even when the DO2 sensor itself is powered. The sensing probe requires a warm-up or stabilization time before returning valid readings. -
Page 18: Reading Via Sdi-12
To force the power off immediately after a reading, for power savings, write a zero to the register. If the power to the entire DO2 sensor is turned off, this value defaults to 30 (or 7.5 seconds). - Page 19 // read: temperature (on board), pressure power <a>D0! <a>+19.1374{crc}<cr><lf> // read: temperature (on probe) For further information and SDI-12 examples, see the Seametrics application note, “DO2 Interface Specification (SDI-12 and Modbus)” available from our web site at: www.seametrics.com Seametrics • 253.872.0284 Page 19...
