Spectro LFP RT - Operating Manual
Chapter 5: Instrument Maintenance
Thanks to its closed construction this instrument requires very little
maintenance.
The external surfaces of all optical parts should be cleaned every now
and then. Please bear in mind that the high-quality reflection optics in
particular are very sensitive to scratches and, therefore, should only
be cleaned with very fine brushes or compressed air!
5.1 Changing white calibration standard
Replace the reference white of the Spectro LFP RT 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.
