3.5 Checking the mains voltage
The following Safety recommendations must be observed when
connecting the balance to the mains:
3.6 Levelling the balance
To function properly, the balance must be precisely horizontal.
The balance is fitted with one „bubble level” and two or four adjust-
able feet for level-control, with the aid of which it is possible to com-
pensate for small height differences and/or unevennesses in the sur-
face on which the balance is standing.
The screw feet must be adjusted so that the air bubble is precisely in
the centre of the sight glass of the bubble level (see Fig. 3.2 Correct
levelling with the aid of the bubble level).

DANGER
The balance may only be operated with the power adaptor
supplied.
Check before connecting the power adaptor to the mains supply,
that the operating voltage stated on the power adaptor agrees
with the local mains voltage.
If the operating voltage is not the same as the mains voltage, the
power adaptor must on no account be connected to the mains
supply. Contact the Precisa-Customer Service.

NOTE
In order to get exact measurements, the balance must again be
carefully levelled after each relocation.
