8. Maintenance

8.1 Bolts tightening
Periodically check the tightness of all the fixing nuts.
If necessary, ensure correct tightening by applying the
tightening torques shown in the table in paragraph 3.5.3.

8.2 Grounding check

Periodically check the earth connections, especially
the integrity of the cables and terminals and remove any
oxidation from the contacts.
8.3 Cleaning of the ebonite coatings
Cleaning and degreasing organic coatings is a delicate
matter. In the case of ebonite-coated Euromisure flow

9. Troubleshooting

For the Troubleshooting section (Problems / Causes / Solutions), please refer to the instruction manual of the converter
associated with the specific sensor.

meters, please avoid any acid solution containing HF
(hydrofluoric acid) in any concentration.
The basic solution, such as NaOH, can be used, but only
at room temperature. Normal soap is recommended for
removing grease and oil.
If cleaning with soap is not sufficient, washing with
a solvent can also be carried out, using products which
evaporate rapidly, for example, acetone. In this case,
the dirt must be removed with a cloth moistened with
acetone, an operation that must be done quickly to avoid
aggression on the Ebonite, and immediately afterward,
the surface must be dried with a blow of air to allow the
solvent evaporation.
