CHAPTER 1
– How to use TECHKON SpectroDens
1.5 Care and maintenance
SpectroDens is a highly-precise optical instrument. It is designed to work in harsh,
industrial environments. However, it should be handled with care. Avoid mechanical
shocks, heat, dusty or humid environments! Keep it always at a safe place, for example
in the carrying case.
Cleaning
The measurement head with the optical system is sealed against dust and dirt. Take
care that the visible, open measurement aperture is always free of dust. You can clean
the measurement aperture with oil-free, clean compressed air and a brush used for
cleaning photographic equipment. For easy cleaning the aperture can be taken off
from the measurement head by unscrewing three screws with a special TORX T6
screwdriver (which is part of the package of a spare aperture set).
Clean the device casing and the display window only with a soft cloth and a non-
aggressive plastic cleaner. Never use alcohol or chemically aggressive solvent-based
cleaners which can destroy the surfaces. The same procedure is valid for the white
standard which is integrated in the charging console. If the white standard should be
defective, it has to be replaced completely.
Should the display window show small scratches, these can be polished out with spe-
cial display polish greases as they are e. g. available for mobile phones and other elec-
tronic equipment as well.
Please do not stick any labels at the bottom of the device. This could lead to faulty
measurements, because the direct contact – which is important for the correct opti-
cal field of depth – might not be maintained. The battery charge can be affected by
a label as well.
