3 Basic Operation


Attaching the dissolved oxygen (DO) sensor
1.
Remove the membrane cap mounted on the DO sensor beforehand, and replace it
with the new membrane cap provided. Replace the internal solution with fresh
solution. The main component of the internal solution is potassium chloride (KCl),
so the old solution can be disposed of down a sink or other drain.
Reference
“ 4.6 Replacing the membrane cap ” (page 89)
2.
Screw in the DO sensor to attach it, allowing the internal solution to overflow
slightly.
3. Use a soft cloth to wipe off the internal solution that overflowed onto the DO
sensor.
4.
Remove the sensor guard.
5.
Remove the sensor plug.
6.
Coat the DO sensor O-ring with a thin layer of grease (part No. 3014017718).
Note
Be sure no grease from the O-ring gets on the sensor connector. If the sensor connector gets grease
on it, wipe it off with a soft cloth soaked in alcohol.
7. Make sure there is no moisture on the sensor probe’s sensor connector (marked
"DO").
8.
Fasten the DO sensor securely using the spanner for DO sensor.

Hold the DO sensor with the provided spanner for DO sensor and push the sensor
down. (Step 1 in figure below)

Screw the DO sensor in place. (Step 2 in figure below)
Note
Do not throw away the white cap which has been put on the tip of the sensor. It will be used for the
storage.
