1.
Attach the Oxygen Probe by installing the "Probe Plug" (Fig. D-1) into the "DO
Socket" (Page 4, Fig. A-15).
2.
Power on the meter by pressing the "Power" button once.
3.
Keep pressing the "Mode" button until the bottom rigth display shows "%O2".
CAUTION! Ensure calibration on air before measurement.
Wait approx. 2 minute until the reading value stabilises. If the reading value on air is
not within 20.7 to 21.1 (20.9 ± 0.2), then proceed with calibration procedures first.
For calibration procedures, please refer chapter 5.2, page 14. After completing the
calibration procedures, the display should show a value between 20.8 and 21.0 (20.9
± 0.1).
4.
Press the "Function" button once, and the bottom right display will show "mg/L".
Now the meter is ready for the Dissolved Oxygen measurement.
5.
•
Remove the protective cover from the probe head and immerse the probe to a
depth of at least 10 cm in the measured liquid in order for the auto matic
temperature compensation to take effect.
•
Thermal equilibrium must occur between the probe & the measurement sample,
which usually takes to a few minutes if the Temp. difference between the two is
only a few degrees Celsius.
