5.4 Storage
To maintain the operability of the meter and short pH electrode for a long
time, please observe the following instructions:
z Do not store the short pH electrode for a longer period of time without the
watering cap put on. The short pH electrode might be damaged by this.
z If possible, leave the short pH electrode or adapter connected to the meter
and avoid to plug it on or off when it is not necessary. Thus, the watertight
plug-in connector will be well protected.
z To store electrodes for a longer period of time, please follow the
instructions in the operating manual of the electrode.
z For a longer storage period, moisten the sponge in the watering cap with
a few drops of pH 4 buffer solution and put the watering cap on the short
pH electrode.
During a longer storage period, occasionally check the sponge in the
watering cap for sufficient moisture.
