Clean up the weighing chamber: Cautiously wipe away dust and powder with a damp, lint-free of charge fabric ahead of cleansing the weighing chamber. Never blow, as it could transfer dust or sample elements into the hole in the midst of the weighing chamber, where there are inside circuits and electromagnetic force cells. If dust or liquid receives into the circuits, they may not function correct, building the readings unstable.
Contemplate desiccated objects: Objects or elements taken from a desiccator could soak up moisture from your atmosphere, creating them heavier.
