not in use for an extended period

TROUBLESHOOTING

• If there is no display, or you have

erratic readings after having soaked

the electrode in distilled/de-ionized

water for at least 1 hour prior to

calibration, check the continuity of the

batteries by removing them for 1

minute, then reinsert

• Slow Response: Soak the electrode in

tap water for 10-15 minutes, then rinse

with distilled/de-ionized water

• "- -

" displays when the pH sample is

too acidic or too alkaline

• "H" or "L" displays when the

temperature is too hot (H) or too cold

(L)

• No Display: Be sure to press for at

least one second If the problem

persists, see Battery Replacement

(above)

• If your readings are still erratic after

calibration, soak the electrode for 10

to 30 minutes in distilled water

• Note: It is normal for the pH value to

fluctuate quickly when the electrode is

exposed to air and not immersed
