3.4. SETTINGS
It is necessary to level the balance prior connecting it to the mains. To level the
balance turn its feet until an air bubble takes the central position.
The balance shall rest on a surface firmly, each of the feet must be supported.
3.5. MAINTENANCE ACTIVITIES
1. Disassembly a weighing pan and other detachable components (the components differ
depending on a balance type – see Unpacking section). Be careful while detaching the
components so as not to cause any damages to the balance mechanism.
2. Using a dry flannel cloth clean glass parts (mild cleanser may be applied if it does not contain
any abrasive substances) – draft shield disassembly instruction is to be found further down this
section.
3. Using a dry flannel cloth clean disassembled components (mild cleanser may be applied if it
does not contain any abrasive substances).
CAUTION!
Cleaning draft shield while still installed may cause damage of the measuring system.
Cleaning ABS components:
To clean dry surfaces and avoid smutching 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 cleaning process if needed.
In the case when contamination is hard to remove, e.g. adhesive, rubber, resin, polyurethane foam
residues 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 products containing abrasive substances.
Cleaning glass components:
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 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 protofilic solvent (sodium carbonate), to remove BASE use protogenic solvent
(mineral acid of various concentration).
In case of heavy contamination use brush or detergent nevertheless avoid detergents containing
large and hard molecules which could potentially scratch glass panes.
Use soft brush with wooden or plastic handle exclusively to avaoid risk of scratches. Do not use wire
brush.
At the end of the cleaning process rinse the pane using running water first, distilled next.
Rinsing is a necessary cleaning process stage allowing to remove remaining soap, detergents and
other cleansers from the panes prior their reinstallation.
