Page 9: Do Calibration (Saturated Oxygen)
4.2 DO Calibration (Saturated Oxygen) Power on the meter, press key, the meter enters calibration mode, CAL will be flashing at the upper-right corner. Insert the DO electrode to the calibration sleeve, and tighten the sleeve cap. Let the electrode sit for 3 to 5 minutes. When the reading is fully stabilized, press key again to finish the calibration. -
Page 10: Notes About Do Measurement
4.4 Notes about DO Measurement a) When calibrating, the environment temperature and water temperature should be close to each other (≤10˚C). If the difference is large, please dip the electrode into the sample water for about 10 minutes, then calibrate the electrode according to Section 4.2. -

or kimwipe afterwards; rinse off the electrode with distilled water, then shake off excess water; Add some new inner solution into the membrane cap; screw on the cap. Then perform the saturated oxygen calibation according to 4.2 before measuring again. 4.5.4 Replace the membrane cap When the DO electrode’s response time becomes slower, obvious errors occur in measurement, or when the sensitive membrane of DO electrode is wrinkled, cracked or... -
Page 12: Salinity Calibration
1) Polarize the meter for 15 minutes, and then perform the saturated oxygen calibration according to the 4.2. 2) Place the electrode into zero-oxygen water, press key to enter calibration mode. When the stabilized reading is 0.02 ppm to 0.15 ppm after 5 minutes, press again to finish the calibration, then flashing 0.0% will show up, the calibration will be finished in several seconds and 0.00 ppm will show up. -

of manual Barometric pressure compensation. We suggest to reset the value according to the standard barometric pressure table when there is a big change in barometric pressure to ensure the accuracy of barometric pressure compensation (Please see Appendix 2 and Appendix 3). For the procedure of Barometric pressure calibration, refer to 4.9.4. - Page 14 4.9.3 Salinity calibration setting (P2) (a) In P1 mode, press key to enter P2 mode, see picture (4-3). (b) Immerse the DO electrode into 12.88mS/cm calibration solution (sold separately), solution level should exceed salinity electrode; let it stand still after stirring; then press key when the value is stable and smiley face icon appears.
