During the setting process, press the Meas key, the tester will exit the setup menu and return to the measurement mode. If you do not want to calibrate the temperature, press the Enter key to skip the °C/CAL or °F/CAL option. The Reset function will restore the tester back to factory default settings. If enabled, all of the calibration data and selected parameters will be lost or reset, the tester must be recalibrated.

12 Setting the salinity coefficient

In order to get an accurate reading, the salinity of the sample should be specified which is done

with the help of a coefficient.

Salt dissolved in water will influences oxygen content of water. If your sample contains high levels

of salinity, ensure that setting an applicable salinity

coefficient prior to measurement.

· In the measurement mode, press and hold the Cal key for 3 seconds to enter the

setup menu, the display shows

(salinity coefficient) option.

· Press the Cal key again to set the value.

· Press the Enter key to confirm, the display shows the next menu item.

· Press the Meas key to exit the setting and return to the measurement mode.

13 Setting the ambient pressure
To ensure an accurate reading, the ambient pressure must be set in the unit mmHg. The following table will help to convert your ambient pressure into the required unit mmHg on the basis of your current height.

14 DO Calibration in % Saturation Mode
PCE-WO2 10 pocket dissolved oxygen tester can be calibrated quickly in air. In the percentage saturation mode, the tester is able to perform either 1 or 2 points calibration. For single point calibration, we recommend that you perform 100% saturation calibration in the air-saturated water. If the 2 points calibration is selected, the zero oxygen solution needs to be used.

14.1 Single point calibration - 100% saturation
· Make sure that you have selected 1 point calibration in the setup menu.
· Press the Cal key, the tester shows "100% / CAL1".
· Hold the dissolved oxygen probe in the air at 100% relative humidity or place the probe into the air-saturated water for 15 minutes.
· Press the Enter key. Wait for the reading to stabilize, the tester automatically shows END. Single point calibration is completed.

14.2 2 points calibration

· Make sure that you have selected 2 points calibration in the setup menu.
· Repeat the steps 1.2 to 1.4 above. When the first calibration point is completed, the display will show "0% / CAL2". The tester prompts you to continue with second point calibration.
· Immerse the dissolved oxygen probe into the zero oxygen solution, stir the probe gently.
· Press the Enter key to confirm. Wait for the reading to stabilize (this can often take more than 10 minutes), the display automatically shows END. The tester returns to the measurement mode. Calibration is completed.
Performing a percentage saturation
calibration will simultaneously calibrate the corresponding mg/L (or ppm) concentration value.

15 Temperature Calibration
During the measurement process, if the temperature reading displayed differs from that of an accurate thermometer, the tester needs to be calibrated.
· Press and hold the Cal key for 3 seconds to enter the setup menu.
· Press the Enter key until the tester shows °C/CAL or °F/CAL.
· Press the Cal key to enter the temperature calibration mode.
· Press the Cal key again to modify the temperature value (Resolution: 0.5°C).
· Press the Enter key to confirm, the tester shows the next menu item.
· Press the Meas key to return to the measurement mode. Calibration is completed.

16 Dissolved Oxygen Measurement
PCE-WO2 10 pocket dissolved oxygen tester is suitable for measuring the water, wastewater, brine and other liquids. If the sample is belong to the seawater or other water containing large amounts of salt, please setting the salinity coefficient before measurement. Some gas and steam such as chloride, sulfur dioxide, sulfureted hydrogen, ammonium, carbon dioxide and iodin can permeate the membrane via diffusion. So their existence will influence the measurement of dissolved oxygen. If the sample contains the solvent, grease, sulfide and alga, the membrane on the probe will be blocked, damaged or eroded.
· Connect the dissolved oxygen probe to tester and wait for 15 minutes to polarize the probe.
· If necessary, to set the barometric pressure and salinity coefficient in the setup menu (Refer to page 5).
· Immerse the probe in the sample solution, make sure the temperature sensor on the probe is fully immersed.
· Stir the probe gently. Record the measured value when the reading is stable.

17 Auto-Hold

PCE-WO2 10 pocket dissolved oxygen tester contains an Auto-Hold function. If enabled, the

tester will automatically sense a stable reading and lock the

measurements. The

icon appears on the display. If disabled, press the Hold key, the tester

will immediately lock the displayed value. Press the Meas key to resume measuring.

18 Electrode Care and Maintenance

Always keep the membrane of the dissolved oxygen probe is wet or moist.

If you do not use the probe for long periods, please screw off membrane cap and rinse

the cathode, anode and membrane with deionized water, then soak up residual water

on them with filter paper. Install the probe again.

19 Troubleshooting

LCD DISPLAY

CAUSE
DO probe does not connect to tester Measured value is out of range Electrolyte solution is depleted Zero oxygen solution is contaminated

CORRECTIVE ACTION
Check the connector of probe. Check the DO membrane whether clogged, dirty or broken. Refilling electrolyte solution.
Replace the calibration solution.

20 Addendum: Preparation of the Zero Oxygen Solution
Dissolve 500mg of sodium sulfate (Na2SO3) reagent and a small amount of cobalt (II) chloride hexahydrate (CoCl2 · 6H2O) in the 250mL distilled water, mix the solution until the reagent is completely dissolved.
