Power Supply; Setting Up And Aligning The Scale - Seca 645 Instruction Manual And Guarantee

Power supply

The scale is powered by a mains unit and by rechargeable batteries. The scale works in-
dependently of the mains, which is very handy for mobile use.
The LC display and the evaluation electronics have a low power consumption – 2000
weighing operations can be performed with a fully charged battery. Once battery voltage
is no longer adequate, the battery symbol
that battery power is dropping. If the batteries are not charged, battery voltage will ulti-
mately not be adequate for error-free measuring. In this case,
and weighing is no longer possible.
The rechargeable batteries are charged by
the mains unit supplied. For this purpose,
the mains unit needs to be connected to
the mains for at least 24 hours.
Please use only the mains unit supp-
lied or mains units from the seca ran-
ge of accessories. Before plugging the
unit into the socket, check whether the
mains voltage marked on the mains
unit matches local mains voltage.

4. Setting up and aligning the scale

– Place the scale on a level surface.
– Undo the locknuts using the four foot
screws (1).
– Align the scale by undoing the foot
screws. The air bubble in the spirit level
must be right in the centre of the
circle (2).
– Then re-tighten the locknuts (3).
– Ensure that only the feet of the scale are
in contact with the floor. The scale may
not be in contact at any other point.
Important!
The alignment of the base of the scale must be checked and corrected if neces-
sary every time the location of the scale is changed.
