be weighed out into your clean and empty container on your sampling

A CLEAN SCALE IS AN ACCURATE SCALE
All too often ink is dropped onto and down the side
of the weighing pan. This ink will harden and form a stalagmite
type restrictor - like a minute shock absorber. This and any other
type of physical interference with the movement of the weighing
pan on the pan cells, will cause inaccurate weighing. Ink that has
seeped underneath the weighing pan edge and dried is one of the
most common sources of inaccurate weighing.
Often a piece of plastic is taped to the pan to protect
the surface from ink being messed while weighing. Although this
is generally a good practice, too often the tape is attached in
such a way that it restricts the movement of the pan especially
when weighing towards the limit of the scales upper weight.
It is very important that the scale is switched off
when cleaning and that the weighing pan is removed and cleaned separately.
If the pan cannot be removed, then it must be cleaned very carefully.
