11.5 Storage
For longer storage periods we recommend to leave the electrode installed
and to remove the battery and store it separately. Plug the watering cap filled
with the suitable reference electrolyte on the clean electrode (see electrode
operating manual).
If the logger is stored without the electrode, close the electrode receptacle
with the enclosed blind plug to protect the plug connector from dirt and
moisture. When doing so make sure that both O-rings of the blind plug are in
place (pos. 1 and 2 in Fig. 11-1).

Store the logger in a dry place while observing the storing conditions
according to chapter 11.5 S
TORAGE . Low temperatures usually delay the
aging of the electrode.
