Intended use The gage is intended solely for measurement of coating thicknesses. Only accessories approved or recommended by ATORN Service may be con- nected to the gage. Any use beyond this is not the intended use. The risk of damage ensuing there- from is borne solely by the user.
► Operate the gage and accessories only outside of potentially explosive areas! Safety of the electrical equipment Only accessories approved or recommended by ATORN Service may be con- nected to the gage! USB cable Damaged USB cable Kinking or pinching the USB cable can result in a broken wire. Data trans- mission is then no longer possible.
