INSTALLING THE DO MEMBRANE (3.4)
Note: The DO sensor is shipped with a dry shipping membrane to protect the
electrode. A new membrane cap must be installed before the first use.
1. Prepare the O
2
probe solution according to the instructions on the bottle. After
mixing, allow the solution to sit for 1 hour. This will help prevent air bubbles
from later developing under the membrane.
2. Unscrew and remove the probe sensor guard.
3. Unscrew, remove, and discard the old membrane cap.
4. Thoroughly rinse the sensor tip with distilled or deionized water.
5. Fill a new membrane cap with O2 probe solution. Be very careful not to touch
the membrane surface.
6. Thread the membrane cap onto the sensor, moderately tight. A small amount
of electrolyte should overflow.
7. Screw the probe sensor guard on moderately tight.
