Changing White Calibration Standard; The Validity Of The Reference White - Barbieri Spectro Swing Operating Manual

Spectro Swing - Operating Manual

4.3 Changing white calibration standard

Replace the reference white of the Spectro Swing if it is no more valid
or it is somehow damaged. Any scratches, dust or dirt on the surface
of the reference white may affect the accuracy of the instrument.

The validity of the reference white

The validity of the reference white is 24 months from the production
date. See the serial number on the reference white, or if not present,
the serial number of your instrument. The first four characters indicate
the year and the month of production. For example a calibration strip
with a serial number A603198 indicates: Year: A6= 2006, Month: 03=
March. This reference white is valid until March, 2008.
