Preparation for use
Prepare the probe for use before calibration or sample measurement.
1.
Turn the probe soaker bottle cap counter-clockwise to loosen the cap.
2.
Remove the soaker bottle from the probe.
3.
Rinse the reference junctions and glass bulb with deionized water thoroughly to
remove the viscous storage/filling solution completely. Blot dry with a lint-free cloth.
4.
Remove the protective tape from the filling hole before initial use (refer to
Figure 1
on page 2). Dispose of the protective tape.
5.
Add filling solution to the probe as necessary (refer to
Fill the probe
on page 10).
The filling solution must be above the standard solution or sample level during
measurement (
Figure 2
).
6.
Make sure that the filling hole is open during measurement for the proper flow of the
filling solution.
Note: For the best stabilization time, condition the probe for several minutes in the sample
before use.
