Near field suppression
Near field suppression is used to suppress interference that could occur, for example, when
using housing windows or due to contamination of the optics.
If the digital filter has been activated, measurements will only be made from a distance of
2.5 m. The measuring system is disabled in the near field. Deviating measurements may
occur around the outer edge of the filter.
Important
On the NAV310, near field suppression is deactivated by default when delivered. If you in-
stall a NAV310 in a housing (e.g. for explosion protection), then you must configure the near
field filter in SOPAS ET.
A feature of the NAV310 allows near field suppression for individually configured sectors to
be enabled/disabled via a telegram, e.g. if a reference measurement is to be carried out in
the near field. See the telegram listing downloadable at sick.com.
