Operating manual
3.1 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 re-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 small as possible (see Chapter 7 .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).
3.2 Scope of delivery
Inspect delivery for completeness immediately on unpacking all components.
Checklist for complete delivery

3.3 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.
3.4 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
3.5 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.
14
3.6 Leveling the weighing machine
*** Not applied to model HRB(-E) 3001 / 6001 / 10001
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. 1)
Place the scale horizontally and keep the bubble inside the bubble level aligned with the red circle (See
Fig.1). In order to get exact measurements, the balance must again be carefully leveled after each
relocation.
Fig. 1 Correct leveling with the aid of the bubble level
ER
3.7 Calibration of the weighing machine
Since the Earth’s gravity is not the same everywhere, each balance must be adjusted to compensate for
the gravity differences at each location in accordance with the underlying physical weighing principles.
This adjustment process, known as calibration and must be carried out on initial installation and after
each subsequent relocation.
In order to ensure exact measurements, it is recommended that the balance should be calibrated
regularly using a known external calibration weight (see Section 5 below).

6 Maintenance and 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.
21
7 Transport, storage
7.1 Transportation and shipping of the weighing machine
Your weighing machine is a precision instrument. Treat it carefully. Avoid shaking, severe impacts and
vibration during the transportation.
Take care that there are no marked temperature fluctuations during the transportation and that the
weighing machine does not become damp (condensation).
7.2 Storage of the weighing machine
If you would like to take the weighing machine out of service for an extended period, disconnect it from
the electricity supply, clean it thoroughly (see Section 6 .Maintenance and servicing.) and store it in a
place which meets the following conditions:
No violent shaking, no vibrations
Minimum temperature fluctuations
No direct solar radiation
Minimum moisture
The weighing machine should preferably be dispatched and transported in the original packaging to avoid
transportation damage.
The weighing machine should preferably be stored in the original packaging, since this provides optimal
protection for the weighing machine.
