3.4. Maintenance Activities
CAUTION:
Cleaning the weighing pan while still installed may cause damage of the measuring system.
1. Uninstall the weighing pan and other detachable components depending on balance type
(refer to section: UNPACKING AND INSTALLATION) . Be careful while installing the
components so as not to cause any damages to the balance mechanism. Remove the
weighing pan of a microbalance using tweezers.
2. Using handheld vacuum cleaner remove dust from the weighing chamber (recommended
for microbalances).
3. It is possible to disassemble the anti-draft chamber of XA series balances weighing
instruments in order to clean it properly, for disassembly instruction read below.
Cleaning anti-draft chamber 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.
Cleaning powder-coated components:
For preliminary cleaning process stage you need running water or wet sponge featuring
large holes, this will help you to remove loose, heavy dirt.
