Buffers for calibration should be based on the measurement range.
Follow the calibration procedure properly.
Be sure to remove air bubbles from pH glass bulb for accurate measurements.
Store the meter and all test materials out of direct sunlight, heat, and away from
chemical storage areas.
Minimize exposure of meter and calibration solutions to heat above 100°F (38°C).
Dry the outside of the meter when testing is complete or before storage of the meter.
Pour pH 4.0 buffer solution up to the "FILL" line of the storage cap. Always store
the pH probe in clean 4.00 pH buffer solution.
Do not store the pH probe in a distilled or deionized water. This will cause
permanent damage to the probe.
Always fi ll the sample collection bottle with enough sample to completely
immerse the probe.
Rinse pH probe properly before putting in storage solution.
The meter has an automatic shut-off after 8 minutes of idle time.
This meter performs best in pool and typical tap water and does not give
reliable readings in distilled or deionized water.
Remove batteries when meter is not used for more than a month (Warranty Requirement).
Do not touch or rub the pH glass bulb.
To avoid cross-contamination, rinse the probe properly with clean water in
between measurements.
To clean the ORP sensor, dip the probe into 0.1 mol/L dilute hydrochloric
acid for 30 minutes; clean the platinum surface with dishwashing liquid; or use
plain white toothpaste to gently clean the platinum surface. Then, rinse with
clean water and soak for 6 hours in the KCl storage solution.
