Preparation for use
To prepare the probe for initial use:
1. If a rugged probe, remove the shroud and probe storage cap (refer to Remove the
shroud on page 10).
2. If a standard probe, turn the probe soaker bottle cap counter-clockwise to loosen the
cap. Remove the soaker bottle from the probe.
3. Remove the protective tape from the reference junctions (refer to Figure 1
on page 2). Dispose of the protective tape.
4. If the probe will be used immediately, prepare the probe for calibration or sample
measurement.
5. If the probe will not be used immediately, store the probe (refer to Storage
on page 10).
To prepare the probe for calibration or sample measurement:
1. If a rugged probe, remove the probe storage cap.
2. If a standard probe, turn the probe soaker bottle cap counter-clockwise to loosen the
cap. Remove the soaker bottle from the probe.
3. Rinse the reference junctions and glass bulb thoroughly with deionized water to
remove the 3 M KCl solution completely. Blot dry with a lint-free cloth.
4. For the best stabilization time, condition the probe for several minutes in the sample
before use.
5. If a rugged probe, make sure that the shroud is installed before field use (refer to
Install the shroud on page 10).
