Preparation for use
To prepare the probe for initial use:
1. Turn the probe soaker bottle cap counter-clockwise to loosen the cap. Remove the
soaker bottle from the probe.
2. If the probe will be used immediately, prepare the probe for calibration or sample
measurement.
3. If the probe will not be used immediately, store the probe ( Storage on page 9).
To prepare the probe for calibration or sample measurement:
1. Turn the probe soaker bottle cap counter-clockwise to loosen the cap. Remove the
soaker bottle from the probe.
2. 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.
3. Rinse the reference junction 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.
Calibration
Before calibration:
The probe must have the correct service-life time stamp. Set the date and time in the meter before the probe is attached.
It is not necessary to recalibrate when moving a calibrated probe from one HQd meter to another if the additional meter is
configured to use the same calibration options.
To view the current calibration, push , select View Probe Data, then select View Current Calibration.
When two probes are connected, push the UP or DOWN arrow to change to the single display mode in order to show the
Calibrate option. (Available only on HQ40d and HQ440d meters.)
Prepare the probe for use (refer to Preparation for use on page 2).
