3 Getting started with your weighing machine
!
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

3.3 Assembling your weighing machine
!14
!
!
!!
The weighing machine is delivered in partly dismantled condition. Assemble the individual components in
the following sequence:
−
−
Place the unit holder in position.
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.
IMPORTANT NOTE: DO NOT TURN THE INDICATOR ON UNTIL ALL CONNECTIONS ARE MADE. IF
THE INDICATOR IS ON PRIOR TO MAKING CONNECTIONS, AND THE CONNECTIONS ARE MADE,
DAMAGE MAY OCCUR.
!
!!
Please complete the following steps before using the scale:
!15
!!
!!
!!
Step1: Connect the cable to the load cell and plug the metal connectors under power off condition.
!
!
!
!
!
Step 2: Adjust the four scale feet horizontally.
!
!
!
!
!
!
!
!
!
!
!
!
3.6 Calibrating 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.
!16
!
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).

5 Calibration - Using an External Calibration Weight
Calibration is generally required when the weighing machine is initially installed or if the weighing
machine is moved to a substantial distance from the original location. 30 minutes of warming up of the
scale is always needed before initial calibration.
A reminder when operating our larger capacity scales:
!
The WB series are calibrated at the factory. Usually no recalibration is necessary unless major
inaccuracies are observed. If calibration is deemed necessary, an appropriate test weight of at

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.
!
!
!
See Section 1.3 above regarding IP65. The scale may be washed down.
!
!
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.
!!
!23
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
