Prior to Use
Filling the Electrolyte Solution
1.1 Take out the dissolved oxygen electrode and electrolyte solution
from the packaging. Unscrew the membrane cap from the bottom
of the electrode, rinse the inside and outside with distilled water
and blot dry.
1.2 Fill the membrane cap halfway with electrolyte solution.
1.3 Screw membrane cap back onto the electrode. Some electrolyte
solution will overflow during this process.
1.4 Check the electrode, ensure that no air bubbles are trapped in the
electrolyte solution and the membrane is not creased or damaged.
Polarizing the Electrode
2.1 Connect the dissolved oxygen electrode to the meter (refer to the
Connection section on page 6).
2.2 Switch on the meter and wait 10 minutes for the electrode to
polarize.
Selecting the Measurement Mode
Press the Mode key until the icon and measurement unit mg/L
or ppm appears on the display, the meter enters the dissolved oxygen
concentration mode.
Press the key again, the measurement unit will switch to %, the meter
enters the percentage saturation mode.
