TROUBLESHOOTING
1. If there is no display, or you have erratic
readings after having soaked the electrode in
KCL (potassium chloride) solution for at least
1 hour prior to calibration, check the continuity
of the batteries by removing them for 1 minute,
then reinsert.
2. Slow Response: Soak the electrode in KCL
(potassium chloride) solution for 10-15 minutes,
then rinse with distilled/de-ionized water.
3. “- - -” displays when the pH sample is too acidic
or too alkaline.
4. No Display: Be sure to press for at least one
second. If the problem persists, see Battery
Replacement (previous page).
5. If your readings are still erratic after calibration,
soak the electrode for 10 to 30 minutes in KCL
(potassium chloride) solution.
6. Note: It is normal for the pH value to fluctuate
quickly when the electrode is exposed to air
and not immersed.
