Maintenance
16.1 Cleaning the pyrometer lens/protective glass
A false temperature reading will be generated when the lens/protective
glass is dirty. Therefore check the lens periodically and clean it, if neces-
sary.
Dust can be removed by simply blowing it away or by using a soft brush.
A special lens cleaning cloth is ideal, but any soft, clean, lint-free cloth
will be suitable.
If the lens is quite dirty, use a very mild liquid detergent and rinse careful-
ly with clear water while holding the pyrometer down. Apply as little pres-
sure as possible to avoid scratching the lens.
Make sure to turn off the pyrometer before removing or attaching the
lens. Failure to do so may result in damage to the instrument!
