CAUTION!

Before carrying out any maintenance, switch off the instrument and disconnect
mains supply.
• Check once a year the calibra on of your instrument. Frequency of recalibra on depends on the
use of the instrument and the ambient condi ons. However, we suggest recalibra on every year.
• Check that all holes and inserts of the instrument are cleaned. Any liquid or oil inside the well
can make oxides or verdigris on the insert during the use at high temperature. In this case the
insert may become stuck.
• Clean the instrument only when it is cold (equal to ambient temperature).
• Clean the instrument with a damp cloth, never use solvents.
• Pay a en on that no liquid may penetrate the instrument, this cause damage or create
poisonous fumes.
