Safety recommendations
When using the weighing equipment in surroundings with increased safety
requirements, the corresponding regulations must be observed.
The weighing scale may only be used with the power adapter supplied.
Before connecting the power adapter to the scale, the user must ensure that the

If not, please contact Customer Service at the address above.
If the power adapter or its cable is damaged, the weighing scale must immediately be
disconnected from the electricity supply (pull out the power adapter).
If there should be any reason to believe that it is no longer safe to operate the scale, it
should be immediately unplugged from the electricity supply (pull out power adapter)
and secured against inadvertent operation.
In carrying out maintenance work, it is essential to follow the recommendations set out
in maintenance and servicing.
The weighing scale must not be operated in an area subject to explosion risks.
Care must be taken when weighing liquids to ensure that no liquid is spilled into the
inside of the scale or into connections on the rear of the equipment or the power
adapter. If liquid is spilled on the scale, it must immediately be unplugged from the main
electricity supply (pull out power adapter).
The weighing scale may be operated after it has first been inspected by a service
technician.

Getting Started
The scale is packaged in an environmentally-friendly carton, which provides optimum
protection for the balance during transportation.
We suggest that you keep the original packaging in order to avoid damage if you are
shipping or transporting the scale to a different location. It is also the best way to keep it
in the best conditions if it will not be used for an extended period of time.
In order to avoid damage, please follow the instructions provided below, when
unpacking the scale:
Unpack the scale carefully.
When outside temperatures are very low, the scale should be stored for a couple
hours and kept in its box in a dry room at normal temperature, so that no
condensation settles on the unit when opening the box.
Check the scale immediately after unpacking for any external visual damage. If
there is any damage on scale, contact customer service immediately.
If the scale is not to be used immediately after purchase, it should be stored in a
dry place where fluctuations in temperature are low. (Reference pg.).
Read through these operating instruction, before you work with the unit and pay
attention to the Safety recommendations (reference Safety pg. 6).

Assembly & Installation
The weighing scale is delivered in a partly dismantled condition. Assemble the individual
components in the following sequence:
Place your machine on a level, clean, and dry surface to obtain accurate
readings.
Place the plastic platter on top of the scale, flat side facing up so the platter
sits firmly on the machine with the four “legs” inserted into the corresponding
four receptacles.
Place the stainless steel platter on top of the plastic platter with the flat side
facing up.
Unwrap and place the clear plastic bowl, open side facing up, on top of the
stainless platter.
Connecting the AC Adapter
The following Safety recommendations must be observed when connecting the balance:
The Scale should only be connected to the mains voltage socket with the power adapter
supplied. Check before connecting the power adapter to the mains socket, that the
operating voltage stated on the power adapter complies with the local mains voltage.
If the operating voltage is not the same as the mains voltage, the power adapter must
not be connected to the mains socket and contact customer service.
Placement of Scale
The location in which the scale is placed is very important in order for the scale to work
to its full potential. Certain conditions can affect the capabilities of the scale, conditions
like: the presence of air flow, variations in temperature, and direct sunlight. Please
follow the recommendations given below in choosing a location to place your scale.
Place the scale on a solid, firm and preferably vibration-proof, horizontal base
Make sure that the weighing machine cannot be shaken or knocked over
Protect from direct solar radiation
Avoid drafts and excessive temperature fluctuations
Avoid placing the scale near or on any magnetic surfaces.
