Observe the following points when handling the verification filters:
 When not in use, the verification filters should always be kept
in the provided box.
 Avoid soiling of the optical surfaces as far as possible.
 The optical surfaces must not come into contact with hard ob-
jects as these can scratch the optical surfaces.
 Dirt or scratches on the optical surfaces change the optical
properties of the verification filters and may make recertifica-
tion or even replacement of the verification filters necessary.
The calibration certificate is valid for two years from the date of is-
sue. Please contact your local SWAN dealer if recertification or in-
spection of your verification filters is required. When returned for
recertification, the verification filters are measured as received be-
fore cleaning and recertification. The data of this measurement are
available on request.
