When not in use, all electrodes should be soaked in distilled
water. If the meter is out of use for a long time, do the
following:
• Disconnect the power adaptor from the power line to
avoid damaging the power adaptor and the meter.
• The socket of the meter must be kept clean and dry.
Avoid contact of the socket with acidic, alkaline, and salt
solution.
• If disconnecting the pH electrode, install the short- circuit
plug onto the meter to prevent damage to the meter.
• Store the electrode in reference filling solution. For
refillable electrodes, plug the filling hole. If the electrode
is out of use for a long time, put it back in the box and
store it at ambient temperature.
