Section 4 Preparation for use
N O T I C E
Make sure to remove the protective tape from the reference junction of new rugged probes. A probe
with a blocked reference junction will not operate correctly.
New probes come with a soaker bottle that contains storage solution to keep the glass bulb and
reference junction hydrated. New rugged probes come with protective tape over the reference
junction. Prepare the probe as follows.
1. Remove the soaker bottle or probe storage cap from the probe. Refer to Figure 2.
2. If a rugged probe, remove the protective tape from the reference junction. Refer to Figure 2.
3. Rinse the probe sensors and reference junction with deionized water. Blot dry with a lint-free
cloth.
4. For faster stabilization, soak the probe for 3 or more minutes in the sample before use.
5. Make sure that the meter has the correct date and time settings. The service-life time stamp in
the probe comes from the date and time settings in the meter.
Note: Some meters automatically open the date and time settings when the meter starts for the first time, or
after battery replacement.
6. Connect the probe to the meter.
