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
The pyrometers are equipped with one optics which can be replaced by optics of the same type
(dependent on the measuring range). For that reason optics for different measuring distances
can be used without recalibration of the instrument. Replacement can be necessary if the lens is
scratched or if the pyrometer will be used for another measuring distance.
Optics replacement:
A suitable objective wrench is required to replace the
optics. The replacement optics consists of the lens support
and a fixed lens. A sticker with the optics data is glued
inside the lens support
