6. MAINTENANCE
Except for the batteries, the instrument contains no parts that can be replaced by personnel who have not been
specially trained and accredited. Any unauthorized repair or replacement of a part by an “equivalent” may grave-
ly impair safety.
6.1. CLEANING
Switch the instrument off.
Use a soft cloth, dampened with soapy water. Rinse with a damp cloth and dry rapidly with a dry cloth or forced air. Do not use
alcohol, solvents, or hydrocarbons.
6.2. REPLACEMENT OF BATTERIES
The symbol indicates the remaining battery life. When the symbol is empty, all of the batteries must be replaced.
Disconnect everything connected to the instrument and switch it off.
Refer to §1.4 for the replacement procedure.
Spent batteries must not be treated as ordinary household waste. Take them to the appropriate recycling collection
point.
6.3. MAINTENANCE
The sensor must not be exposed to volatile chemicals such as solvents or other organic compounds. If the concentration of the

hydrogen peroxide, etc.
