12.1 Cleaning the lens

A false reading will be given when the lens is dirty.
Therefore check the lens periodically and clean it, if nec-
essary.
Dust can be removed by simply blowing it away or by us-
ing 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 carefully with clear water while holding the de-
vice pointed down. Apply as little pressure as possible to
avoid scratching the lens.
