outlet that is easily accessible.
ð The balance is ready for use.
Note
Always connect the AC/DC adapter to the balance before connecting to the power.
Do not connect the instrument to a power outlet controlled by a switch. After switching on the instrument, it must
warm up before giving accurate results.
4.5.2 Switching on the balance
Before using the balance, it must be warmed up in order to obtain accurate weighing results. To reach operating
temperature, the balance must be connected to the power supply for at least 30 minutes (60 minutes for 0.1mg
models).

4.5.4 Leveling the balance
Exact horizontal and stable positioning are essential for repeatable and accurate weighing results.
The balance can be levelled using the leveling assistant and/or the level indicator in front of the balance. There
are two adjustable leveling feet to compensate for slight irregularities in the surface of the weighing bench.
The balance must be leveled and adjusted each time it is moved to a new location.
4.5.4.1 Leveling the balance using the level indicator
All balances have a level indicator with an air bubble that can be used level the balance manually.

4.5.5 Adjusting the balance
To obtain accurate weighing results, the balance must be adjusted to match the gravitational acceleration at its
location. This is also dependent on the ambient conditions. After reaching the operating temperature, it is
important to adjust the balance in the following cases:
• Before the balance is used for the first time.
• If the balance has been disconnected from the power supply or in the event of power failure.
• After significant environmental changes, e.g., temperature, humidity, air draft or vibrations.

Environmental recommendations
• Windowless, non air-
conditioned room,
e.g., basement.
• Only one person in the
weighing room.
• Sliding doors.
Standard doors cause
pressure changes.
• No draft in weighing
room (check with
suspended threads).
• No air conditioning
(temperature
oscillates, draft).
• Acclimatize balance,
take dummy
measurements.
• Instrument uninter-
ruptedly connected to
the power supply (24h
per day).
Select location according
to "Selecting the
location" (customer
responsibility).
