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.
