Getting started
Unpacking the equipment
The machine is delivered in an environmentally-friendly carton, specifically developed
for this precision instrument, which provides optimum protection for the balance during
transportation.
We suggest that you retain the original packaging in order to avoid transportation
damage if shipping or transporting the balance and to allow the unit to be stored in the
best conditions if it is out of operation for
an extended period.
In order to avoid damage, attention must be given to the following points when
unpacking the balance:
Unpack the weighing machine carefully. It is a precision instrument.
When outside temperatures are very low, the balance should first be stored for some
hours in the unopened transport package in a dry room at normal temperature, so that
no condensation settles on the
unit when unpacking.
Check the weighing machine immediately after unpacking for externally visible damage.
If you should find transport damage, please inform your service representative
immediately.
If the unit is not to be used immediately after purchase but only at a later time, it should
be stored in a dry place where fluctuations in temperature are as low as possible (see
Chapter 12 .Transport, storage.).
Read through these operating instructions, even if you already have prior experience
with weighing equipment, before you work with the unit and pay attention to the Safety
recommendations (see Chapter 1 .Safety).
Scope of delivery
Inspect delivery for completeness immediately on unpacking all components.

Rev 4, 04.25.2019
Assembling your weighing machine
The weighing machine is delivered in partly dismantled condition. Assemble the
individual components in the following sequence:
−Place the unit holder in position and add the weighing pan
−Insert the power adapter cable plug into the socket at the rear of the balance.
Choice of a suitable location
The environment in which your weighing machine is used is very important. Air
movement, temperature changes, vibrations, direct sunlight, etc. all influence the
performance of high precision weighing machines. Therefore, place your weighing
machine on a solid, sturdy surface that is free of air currents, vibration and not in direct
sunlight. The surface should not be magnetic and should be located away from doors,
windows, heaters, air conditioners and fans.
To summarize:
−Put the weighing machine 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
Checking the mains voltage
The following Safety recommendations must be observed when connecting the balance
to the mains:
The balance may only be operated with the power adapter supplied.
Check before connecting the power adapter to the mains supply, that the operating
voltage stated on the power adapter agrees with the local mains voltage.
If the operating voltage is not the same as the mains voltage, the power adapter must
on no account be connected to the mains supply. Contact customer service.

13
Rev 4, 04.25.2019
Leveling the weighing machine
To function properly, the balance must be precisely horizontal. The balance is fitted with
one bubble level. and adjustable feet for level-control, with the aid of which it is possible
to compensate for small height differences and / or any unevenness in the surface on
which the balance is positioned.
The screw feet must be adjusted so that the air bubble is precisely in the center of the
sight glass of the bubble level (see Fig. 3.2)
Place the scale horizontally and keep the bubble inside the bubble level aligned with the
red circle (See
Fig.3.2). In order to get exact measurements, the balance must again be carefully
leveled after each relocation.
Fig. 3.2 Correct leveling with the aid of the bubble level
Calibration of the weighing machine
Since the effect of the Earth’s gravity is not the same everywhere every balance must
be adjusted to compensate for the gravity differences at each location in accordance
with the underlying physical weighing principles which apply to accurate weighing
machines. This adjustment process is known as calibration and must be carried out on
initial installation, regularly in accordance with internal quality systems and after each
subsequent relocation.
In order to ensure best measurement results it is recommended that the balance should
be calibrated regularly and often using a known external calibration weight (see Section
5 below).

Rev 4, 04.25.2019
Maintenance & Service
The weighing machine must be treated carefully and cleaned regularly. It is a precision
instrument.
For maintenance-work, the balance must be separated from the power supply (remove
power adapter plug from socket). Also ensure that the balance cannot be reconnected
to the power
supply during the work by a third party.
Take care during cleaning that no liquid penetrates into the appliance. If liquid is spilt on
the balance, the latter must immediately be disconnected from the electricity supply.
The balance may
only be used again after it has first been checked by a service engineer.
The connections on the rear of the appliance and the power adapter may not come into
contact with liquids.
Regularly dismantle the weighing pan and the weighing pan holder and remove any dirt
or dust from under the weighing pan and on the weighing machine housing with a soft
brush or a soft, lint-free cloth, moistened with a mild soap solution. The scale and the
holder can be cleaned under running water. Take
care that both parts are completely dry before they are re-installed on the scale.
Never use solvents, acids, alkalis, paint thinners, scouring powders or other aggressive
or corrosive chemicals for cleaning, since these substances attack the surfaces of the
scale housing and
can cause damage.

19
Rev 4, 04.25.2019
