Design and Function 9Semi-Micro Balances
4 Installation and Putting into Operation
4.1 Selecting the location
A balance is a sensitive precision instrument. The location where it is placed will have a profound effect on the
accuracy of the weighing results.
Requirements of the location
According to the environmental condition, see chapter "General data".
Ensure there is:
• indoor on
stable table
Avoid:
• direct sunlight • vibrations • strong drafts • temperature
• with sufficient
distance (>
15 cm)
• in level • adequate lit
fluctuations
4.2 Scope of delivery
• Balance with draft shield
• Weighing pan with pan support
• Draft ring
• Drip tray
• Protective cover
• AC/DC adapter
• Power cable (country specific)
• 1 User Manual
• Declaration of conformity
4.3 Unpacking
Open the balance packaging. Check the balance for transport damage. Immediately inform a METTLER TOLEDO
representative in the event of complaints or missing accessories.
Retain all parts of the packaging. This packaging offers the best possible protection for transporting the
balance.

CAUTION
Injury due to breaking glass
Careless handling with the glass components can lead to breakage off glass and damage
cuttings.
− Always proceed focused and with care.
Push the side glass doors back as far as will go and place the following components on the balance in the
specified order:
1 Place the drip tray (1) into the correct position.
2 Place the weighing pan (3).
3 Place the draft ring (2).
4.5 Connecting the balance
WARNING
Death or serious injury due to electric shock
Contact with parts that carry a live current can lead to death or injury.
1 Only use the approved METTLER TOLEDO power supply cable and AC/DC adapter with a
current-limited SELV output.
2 Connect the power cable to a grounded power outlet, ensure correct polarity.
3 Keep all electrical cables and connections away from liquids and moisture.
4 Check the cables and power plug for damage and replace damaged cables and power
plugs.
NOTICE
Damage to the AC/DC adapter due to overheating
If the AC/DC adapter is covered or in a container, it is not sufficiently cooled and will
overheat.
1 Do not cover the AC/DC adapter.
2 Do not put the AC/DC adapter in a container.
The balance is supplied with an AC/DC adapter and a country-specific power cable.
• Install the cables so that they cannot be damaged or interfere with operation.
• Insert the power cable in a grounded power outlet that is easily accessible.

the back of your balance (see figure) and to the power
line.
2 Screw the plug tight to the balance.
ð The balance is ready for use.
4.6 Setting up the balance
4.6.1 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 acclimatized and connected to the power supply for at least 60
minutes.
Switching on
− Press On.
ð The balance performs a display test. All segments
in the display light up briefly, WELCOME and
software version. Maximum load and readability
appears briefly. (Startup FULL mode only).
ð The balance is ready for weighing or for operation with
the last active application.
Legal-for-trade
Approved balances will execute an initial zero.
4.6.2 Leveling the balance
The balance has a level indicator and two adjustable leveling feet to compensate for slight irregularities in the
surface of the weighing bench. The balance is exactly horizontal when the air bubble is in the middle of the
level glass.
The balance must be leveled and adjusted each time it is moved to a new location.
To level it, proceed as follows:
1 Position your balance at the selected location.
2 Align the balance horizontally.
Installation and Putting into Operation12 Semi-Micro Balances
C
È
3 Turning the two front leveling screws of the housing
until the air bubble is in the inner circle of the level
indicator.
Example
Air bubble at 12 o'clock: turn both feet clockwise.
Air bubble at 3 o'clock: turn left foot clockwise, right foot counterclockwise.
Air bubble at 6 o'clock: turn both feet counterclockwise.
Air bubble at 9 o'clock: turn left foot counterclockwise, right foot clockwise.
4.6.3 Left/right operating of the glass draft shield
The glass draft shield of your balance can be adapted to the environ-
mental conditions and your weighing style, as well as to the type of
weighing and loading.
The position of the handles determines which door(s) of the draft
shield (left, right, or both) is/are opened.
Try various different combinations by moving the external handles into
the upper or lower position. We recommend you to set up the glass
draft shield so that it only opens on the side where the balance is
loaded. Your balance then works faster, because there are fewer
troublesome currents of air than when both doors of the draft shield are
opened together.
4.6.4 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).
• At regular intervals during weighing service.

4.7.4 Customer fine adjustment
NOTICE
This function should be executed only by trained personnel.
The function customer fine adjustment ADJ.CUST.F allows you to adjust the value of the internal adjustment
weight with your own adjustment weight. The adjustable range of the adjustment weight is possible only in a
very small range. Customer fine adjustment impacts the function of internal adjustment. The customer fine
adjustment can be deactivated at any time.
Note
• This feature is available on models with internal weight only.
• Because of certification legislation, approved models cannot be adjusted with customer fine adjustment
(depending on selected countries' certification legislation).
• Use certificated weights.
• Balance and test weight have to be on operating temperature.
• Observe the correct environmental conditions.
