Should the electronics be opened, any warranty will become invalid. As soon as the external power supply to the instrument is switched on, a green LED will indicate that the unit is ready for operation. Page 8 DF-MA K08/1123...
Caution 10. Maintenance For measured media without contamination, the DF-MA instrument is almost maintenance-free. As the rotating vane contains magnets, any ferritic particles present in the medium may lead to problems. In order to avoid such problems, we recommend the installation of a magnet filter e.g.: model filter MF-R.
