Abstract
In a balance (10) for weighing blister packs (50) in the microgram weight range, its balance pan (12, 14) is designed in such a way that field forces (70) caused by an electric field act practically exclusively on the balance pan (12, 14), said field being generated by an electrically charged blister pack (50) lying on the balance pan.

- with a blister pack (50) made of chargeable material,
- characterized in that
- the balance pan (12, 14) is designed in such a way that field forces (70) caused by an electric field act practically exclusively on the balance pan (12, 14), which field can be generated by an electrically charged blister pack (50) lying on the balance pan.
The balance as claimed in one of the preceding claims,
- characterized in that
- the balance pan (12, 14) and/or the body (18) is grounded.
The balance as claimed in one of the preceding claims,

- the balance pan (12, 14) has a three-point support (12) for the at least one blister pack (50) to be weighed.
The balance as claimed in one of the preceding claims,
- characterized in that
- the body, in particular the cage (18), has a three-point support for the at least one blister pack (50) to be weighed.
The balance as claimed in one of the preceding claims,
- characterized in that
