7 Maintenance
7.1 Cleaning the front window
Since the device does not contain parts that require regular maintenance, the only regular
maintenance required is periodic inspection of the front window for build-up of foreign
particiles. If allowed to build up, the particles can influence the energy received by the
instrument.
The window is not water soluable and can be cleaned with standard lens tissue dampened with
a commercially available glasses or camera lens cleaning solution. Use a soft blower/brush
(available in camera stores) to remove any grit on the window before you rub the lens with lens
tissue and solution.
Attention: NEVER CLEAN THE WINDOW WITH A DRY TISSUE OF ANY KIND! The
only time dry lens tissue may be used is to dry a window which has already been
cleaned with wet lens tissue.
7.2 Changing of optics or fiber
The pyrometers are equipped ex works with a small or a large optical head. The optical heads
can be changed against each other. If changing the fiber or the optical head a recalibration of
the pyrometer should be done. Replacement can be necessary if the lens is scratched or the
pyrometer will be used for other measuring distances.
