1. Disassembly a weighing pan and other detachable components (the components differ
depending on a balance type – see Unpacking and Installation section). Be careful while
detaching the components so as not to cause any damages to the balance mechanism. It is
recommended to use tweezers while detaching microbalance’s pan.
2. Using handheld vacuum cleaner remove dust from the weighing chamber (recommended
especially for microbalances).
3. You can disassembly anti-draft chamber panes of XA and AS series is order to clean them
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 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.
