4. PROBE PREPARATION
D.O. probes are shipped dry. To hydrate the probe and prepare it
for use, connect it to the meter and proceed as follows.
1. Remove the red and black plastic cap.
This cap is used for shipping purposes
only and can be thrown away.
2. Wet the sensor by soaking the bottom
2.5 cm of the probe in electrolyte
(
MA9071
) for 5 minutes.
3. Rinse the membrane (supplied with the
meter) with electrolyte while shaking it
gently. Refill with clean electrolyte.
4. Gently tap the sides of the membrane
with the finger tip to ensure that no
air bubbles remain trapped. To avoid
damaging the membrane, do not tap the
membrane directly on the bottom.
5. Place rubber O-Ring properly inside the membrane cap.
6. With the sensor facing down, screw the cap clockwise.
Some electrolyte will overflow.
When not in use and during polarization, place the protective cap
supplied with the meter.
