1. Insert the electrode connector into the connector port
sleeve on the meter, after aligning with the pin. Do not
insert the connector unless it is aligned properly with the
connector port.
2. Press the electrode connector into the connector port on
the meter, while turning the connector to the right.
3. Slide the connector cover over the connector. Then,
push the cover in straight until it comes in light contact
with the meter case. Do not turn the cover.
4. Insert the temperature connector into the jack on the

Preparation
Note
White crystal (KCl) can adhere to the internal solution filler port
or protective cap. However, it will not cause any performance
problem.
Wash away the white crystal with pure water (or deionized
water).
For the first use or use after a long interval
1. Loosen the knurled nut, then remove the protective cap.
2. Open the internal solution filler port.
3. Remove the existing electrode internal solution with a
dropper.
4. Fill the electrode with new internal solution (model 300)
until the solution level gets close to the internal solution
filler port.
5. Wipe the responsive glass membrane with filter paper or
tissue paper moistened with a small amount of ethanol,
and rinse it well with pure water (or deionized water).
Then wipe drops with filter paper or tissue paper.
