Warning!
If the measuring instrument falls down or is exposed to any other
comparable mechanical strain, the end connections of the refrigerant
hoses can break off. The valve knobs can also be damaged, which
can lead to further damage in the interior of the instrument, which is
not visible externally. For this reason, replace the refrigerant hoses
after any fall or comparable mechanical strain with new, undamaged
refrigerant hoses. For your own safety, send the instrument to Testo
customer service for technical testing.
