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 adjustable feet
for level-control, with the aid of which it is possible to compensate for
small height differences and/or unevennesses in the surface on which
the balance is standing.
The two screw feet must be adjusted so that the air bubble is preci-
sely 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.
