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
Inspect delivery for completeness immediately on unpacking all components.

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.
13
3.6 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. 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 and adjusting feet.
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).
