Only the wheels should be immersed, therefore, please remove them from the legs before doing it. 
The felt hoops (B) and the felt hoop connector must be saturated before measuring. In normal use (with water and cupper solution),

the thin felt is on the wooden spigot side (A).
Prepare the saturated solution by mixing 40 units by weight of copper sulphate with 100 units by weight of distilled water. Fill in the
c
cupper tank removing the plug (C). Add an additional teaspoon of copper sulphate crystals into the electrode.
The electrode should be filled as completely as possible with a minimum of air in the compartment.
