PROBE CONNECTION & PREPARATION

5. PROBE CONNECTION & PREPARATION
To take measurements, connect the D.O. probe to the meter securely by aligning the pins
with the socket located on the back of the meter, pushing the plug in and tightening the
threaded ring.
Probes shipped from Milwaukee Instruments are 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 for
shipping purposes and can be thrown away.
2. Wet the sensor by soaking the bottom 2½ cm (1”) of the
probe in electrolyte (
MA9071
) for 5 minutes.
3. Rinse the membrane cap (
MA841
supplied in the kit
with the meter) with electrolyte solution while shaking
it gently. Refill with clean electrolyte solution.
4. Tap gently the sides of the membrane cap with your
finger tip to ensure that no air bubbles are trapped. To
avoid damaging the membrane, do not tap it directly
on the bottom.
5. Make sure that the rubber O-ring sits properly inside
the membrane cap.
6. With the sensor facing down, slowly screw the cap
clockwise. Some electrolyte will overflow.
When not in use and during polarization (see OPERATIONAL GUIDE), use the protective
transparent cap supplied in the kit with the meter.
