3.5. Maintenance Activities
In order to clean the weighing instrument risk-free, proceed as follows:
1. Uninstall the weighing pan and other detachable components; (the components differ
depending on a balance model, read section:
UNPACKING AND INSTALLATION
. Be
careful while installing the components so as not to cause any damages to the
balance mechanism.
2. It is possible to disassembly the anti-draft chamber in order to clean it properly - for
disassembly instruction read below.
Caution:
Cleaning the weighing pan while still installed may cause damage of the measuring system.
Cleaning ABS Components
To clean dry surfaces and avoid smudging, use clean non-colouring cloths made of cellulose
or cotton. You can use a solution of water and detergent (soap, dishwashing detergent, glass
cleaner). Gently rub the cleaned surface and let it dry. Repeat the cleaning process if
needed.
In the case of hard to remove contamination, e.g: residues of adhesive, rubber, resin,
polyurethane foam etc., you can use a special cleaning agents based on a mixture of
aliphatic hydrocarbons that do not dissolve plastics. Before using the cleanser for all
surfaces we recommend carrying out tests. Do not use cleansers containing abrasive
substances.
Cleaning Draft Shield Panes
Select dissolvent depending on a dirt. Never soak the glass panes in alkaline solutions since
they interact with glass and may cause damage. Do not use cleansers containing abrasive
substances.
For organic dirt use acetone first, next use water or detergent. For other than organic dirt use
diluted acid solutions (soluble salts of hydrochloric or nitric acid) or base solutions
(ammonium or sodium base).
To remove ACIDS use protophilic solvent (sodium carbonate), to remove BASE use
protogenic solvent (mineral acid of various concentration).
In case of heavy contamination use brush and detergent, nevertheless avoid detergents
containing large and hard molecules which could potentially scratch glass panes.
At the end of the cleaning process rinse the pane using distilled water.
Use soft brush with wooden or plastic handle exclusively in order to avoid risk of scratches.
Do not use wire brush.
Rinsing is a necessary cleaning process stage allowing to remove remaining soap,
detergents and other cleansers from the panes prior their reinstallation.
After preliminary cleaning process stage, rinse the pane using running water first, distilled
next.
Avoid drying the panes either using paper towel or forced air circulation since some fibres,
grains or contamination of other type could permeate into the panes thus causing weighing
errors.
We do not recommend using driers when drying measuring glass tools.
It is a frequent treatment to leave glass components on a rack to dry.
